Due to cracking, mechanical properties of brittle materials (without interruption of cracking) have not been obtained by experiments. A novel method of using single nanoindentation is developed to determine crack-free mechanical properties (elastic m

For simulating multiaxial ratcheting behavior, the modified Chaboche kinematic hardening model was numerically implemented by using the framework of a small-strain elastic-plastic theory. Unlike early models, this improved multiaxial model is difficu
