We implemented, validated, and applied a microstructurally based orthotropic hyperelastic constitutive model to simulate pulmonary artery mechanics under...
A study is made of the effects of superposed tangential force by off-axis indentation loading on curved bilayers consisting of brittle shells filled with...
The competition between fracture modes in monolithic brittle materials loaded in cyclic contact in aqueous environments with curved indenters is examined. Three...
Sol-gel bioactive glasses (BGs) are a type of third generation biomaterial (i.e., materials that are both bioactive and bioresorbable). Recently, sol-gel...
A framework is presented for converged quantum mechanical calculations on large amplitude dynamics in polyatomic hydrides (XH n), based on a relatively simple...
