250 Computational Modelling of Biomechanics and Biotribology
The cast iron plasticity material constitution in ABAQUS nite element
analysis software was used to describe the elastic–plastic behavior with
asymmetric yield strength and hardening in tension and compression of tra-
becular bone material (Bayraktar et al ., 2004; Gong et al ., 2011). In each
nonlinear analysis, the initial apparent yield point was determined using the
0.2% offset method.
8.2.3 Dynamic mechanical behavior of trabecular bone
Previous studies have shown that the mechanical properties of trabecu-
lar bone are dependent on loading: tension and compression behaviors ...
