... on the surface of some kind of hard brittle materials, and the formability aspects of these materials are investigated. By carrying out load/depth analysis on the imprinted surfaces, the critical depths for the materials tested are studied. Variation of indentation depth in an imprinted mark is also discussed...

...Jing Shi; C. Richard Liu In literature, four models incorporating strain rate and temperature effects are able to generalize material test results of HY-100 steel. This study compares the four models, namely, Litonski-Batra, power law, Johnson-Cook, and Bodner-Partom, in finite element modeling...
