Lo, Calvin, Sano, Tomoko, Hogan, James D.
We investigated the uniaxial compressive behavior of damaged and intact alumina using quantitative X-ray computed tomography (XCT) analysis coupled with digital image correlation (DIC) for mechanical characterization. Internal three-dimensional crack characteristics such as crack surface area and...

Density, strain rate and strain effects on mechanical property evolution in polymeric foams
Download2022-03-01
Bhagavathula, Kapil Bharadwaj, Meredith, Christopher S., Ouellet, Simon, Romanyk, Dan L., Hogan, James D.
This study presents a comprehensive experimental study of the evolution of Poisson’s ratio and tangent modulus of polymeric foams during rate dependant uniaxial compression. In this study, polyurethane foams with densities of 195 kg/m3, 244 kg/m3, and 405 kg/m3 obtained from PORON (XRD series)...
