An Internal Digital Image Correlation Technique for High-Strain Rate Dynamic Experiments
Barry P Lawlor, Vatsa Gandhi, Guruswami Ravichandran
Background: Full-field, quantitative visualization techniques, such as digital image correlation (DIC), have unlocked vast opportunities for experimental mechanics. However, DIC ha…
Full-Field Quantitative Visualization of Shock-Driven Pore Collapse and Failure Modes in PMMA
Barry P Lawlor, Vatsa Gandhi, Guruswami Ravichandran
The dynamic collapse of pores under shock loading is thought to be directly related to hot spot generation and material failure, which is critical to the performance of porous ener…
Mesoscale shock structure in particulate composites
Suraj Ravindran, Vatsa Gandhi, Barry Lawlor +1
Multiscale experiments in heterogeneous materials and the knowledge of their physics under shock compression are limited. This study examines the multiscale shock response of parti…
Three dimensional full-field velocity measurements in shock compression experiments using stereo digital image correlation
Suraj Ravindran, Vatsa Gandhi, Akshay Joshi +1
Shock compression plate impact experiments conventionally rely on point-wise velocimetry measurements based on laser-based interferometric techniques. This study presents an experi…
