I often use the Olympic motto Citius, Altius, Fortius — Faster, Higher, Stronger — to describe the overall purpose of my work. I strive to expand the boundaries of my research fields to help create structures, devices, and vehicles that are stronger, lighter, faster and with improved properties. Shock waves are useful tools to generate highly dynamic and extreme conditions to study a range of such fields in fluids and solids. In particular, my research group use shock waves to study fluid-structure interaction under intense loading scenarios. Thus, our research addresses dynamic extremes in the fields of fluid and solid mechanics, including sub-disciplines such as fracture mechanics.

Research Projects

Project: Dynamic fracture of polymers

2013-present

We are interested in the effects of dynamic fracture of polymeric specimens. The goal is to develop a deeper understanding and predict dynamic crack initiation and propagation of polymers and different types of composites subjected to highly transient loading under extreme conditions.

Some of the samples are conditioned such that they have a considerable amount of water uptake before the impact experiment. Experimental edge on impacts onto samples are performed using projectiles launched from a gas gun. The dynamic response of the impacted samples are obtained using strain gauges with simultaneous ultra high-speed visualization techniques featuring a newly acquired Shimadzu Hypervision HPV-X2 camera that is capable of frame rates up to 10 million frames per second. We use different types of visualization techniques, such as digital image correlation, caustics, and photoelasticity, to probe the response of the samples.

So far, we have studied samples made of PMMA, neat vinyl ester resin, polycarbonate and carbon fiber/vinyl ester. Of particular interest is to obtain fracture toughness values obtained under mode-I, mode-II or mixed mode loading.
Caustic imaging of a crack propagating in PMMA
This image shows 9 subsequent high-speed photographs visualizing crack propagation in a PMMA sample conditioned at 11% relative humidity. The location of the crack tip is inside the caustic and the technique used to obtain this image is called caustic imaging.

PROJECT: Shock wave attenuation

2012-present,

The research undertaken in this project is aimed at forming an experimental and numerical foundation to investigate shock wave attenuation. We are interested in effects of shock attenuation due to obstacles placed in the path of the shock wave. Particularly, we are interested in how large vs small geometrical features of the obstacles influence the degree of attenuation. Furthermore, we are interested in learning more about shock mitigation using liquids, and in particular, passive techniques where liquids are placed in the path of the shock wave. In particular, we are looking into

  1. Specific geometric shapes of liquid sheets to understand the optimal degree of attenuation that can be obtained.
  2. We ask ourselves what the role of Newtonian and non-Newtonian fluids and their mass, as well as thermal and inertial properties are on shock attenuation.
Direct measures of shock wave amplitude, peak pressure, total impulse in addition to quantitative and qualitative ultra high-speed shock wave schlieren photography is being used throughout this project.

Shock wave interaction with obstacles placed in a logarithmic spiral pattern
This image shows a series of high-speed schlieren photographs. A planar shock wave, propagating from left to right, impacts onto square obstacles placed along the outline of a logarithmic spiral.


Shock wave impact onto liquid surface
This image shows a series of high-speed photographs taken with a Phantom V711 camera. The incident shock propagates from the upper left corner and impacts onto a water wedge. The incident shock Mach number is 1.52 and the water wedge angle is 47 degrees. A regular reflection occurs.

PROJECT: High rate loading of brain cells

2013-present,

Over the last 70 years many causes of traumatic brain injury (TBI) due to impact have been proposed. These include acceleration-deceleration of the head, intracranial pressure changes, stress waves, relative motion of the brain with respect to the skull, and cavitation. However, these causes utterly fail to describe quantitatively the main cause of injury, which is excessive tissue deformation. In our opinion, it is apparent that there still exists a debate on the main causes of TBI, and injury thresholds still has to be quantitatively understood.

Our long-term research goal is to establish a correlation between quantifiable mechanical parameters, such as deformation, strain and strain rate response, and underlying biological mechanisms responsible for tissue damage and impairment observed after impact events, and thereby improve prevention, diagnosis and treatment of TBI.

  1. We have developed an experimental setup, HAMr, in which brain cells have been impacted under highly controlled settings. Then, both mechanical and biological response have been recorded.
  2. We have also developed a pendulum impactor setup in which more realistic skull geometries can be studied carefully during and after a dynamic impact.
In this project we also use ultra high-speed imaging techniques to capture the dynamic response of the sample.

Outreach Activity

Dr Eliasson was during her time at USC actively particiapting in a variety of outreach projects, both at USC and in the nearby community. Other activities in connection with UCSD and the Department of Structural Engineering will be posted below.

Are you interested in connecting with us through our outreach efforts? Please contact Dr Veronica Eliasson to discuss ideas!

Collaboration with USC VAST (2015 & 2016)

USC Viterbi Adopt-a-School, Adopt-a-Teacher program (VAST) offers STEM programs that target K-12 Schools, K-12 Students, K-12 Teachers, and USC Students. The USC AME Department was featured by VAST in the fall of 2014 and our research group offered 15 lab tours during a single day. Then, as part of the AME Spotlight Event, Prof. Eliasson and PhD student Stelios Koumlis visited I have a Dream LA's 5th graders at 99 St Elementary School and talked about "Shock Wave Adventures" and super heroes. In June 2015, we again visited I have a Dream LA's 5th graders at 99 St Elementary School and launched soda bottle water rockets. How fun!

USC AME PhD students, Master's and Undergraduate students, and two USC Viterbi SHINE High School students launch rockets with 5th graders participaing in a summer program by "I have a Dream LA". Duct tape and carboard boxes can be used for many things!

Summer of 2015 - 8 weeks of SHINE: this is a competitive and unique eight-week opportunity for high school students to participate in hands-on engineering laboratory research focused on real-world problems. Dennis Lin and Alan Ton spent the summer with us and worked on several different experiments. They also used our Phantom V711 camera to record some movies of water balloon impacts, and other things - see below and our YouTube channel.

Summer of 2016 - 8 weeks of SHINE: Again, we had the opportunity to host two high school students, Tyler Amano-Smerling and Shaun Chen, in our lab. Tyler and Shaun worked together with PhD students on their research projects. Among other things, Shaun filmed the launch a soda bottle water rocket at high frame rates, and Tyler shot an arrow through a water-filled balloon and photographed it with a Phantom V711 camera.

Collaboration with IEA (2012, 2013, & 2014)

We worked with the Institute for Educational Advancement (IEA), which is a non-profit organization dedicated to supporting talented young people in pursuing their full academic and personal potential, during the summers of 2012, 2013 and 2014. We participated by housing one or two high school student Apprentices in our laboratory for four to eight weeks during the summers. Here is a Mentor Spotlight on Dr. Eliasson from 2014. Read a feature article from VAST here Dr. Eliasson's research group outreach activities
Alex and Hari, summer 2014, are working on an experimental setup, HAMr, used to determine how cell cultures behave under dynamic impact.

Participation in USC SURE (2014 & 2016)

The summer of 2014 was the first time we participated in the USC Summer Undergraduate Research Experience (SURE). For two months, we had a visiting undergraduate researcher, Michael Werner from Colorado School of Mines, CO, in our group helping us with our research on fracture propagation in polymers conditioned in liquid or humid environments subjected to dynamic impact. Michael then became a PhD student at Georgie Tech. Dr. Eliasson's research group outreach activities
Summer 2014, Michael is working together with our PhD student Orlando to determine how the stress optical coefficient varies in PMMA and vinyl ester sheets as function of absorbed water content.

Other outreach

During the summer of 2016, we hosted two undergaduate students, Fernando Zigunov and Lucas Ravanello Mokwa, from the Brazilian Scientific Mobility Program, in our lab. It was a great experience for everyone involved and we are excited to see what Fernando and Lucas decide to do in the future.

In March, 2015, Professor Eliasson gave a Keynote Lecture on "Shock Wave Adventures" during the 2015 Women in STEAM Celebration to the Lower School Students at Mirman School. In the afternoon, the PhD students in our research group launched soda bottle water rockets with the same students.
