摘要：
A comprehensive 1D constitutive model for bovine trabecular bone is proposed within the framework of standard generalized materials. Linear viscoelasticity is combined with a constitutive law describing damage. Trabecular bone specimens, extracted from fresh proximal tibias and distal femurs of mature cows, were subjected to relaxation, creep and cyclic compressive tests. The constitutive model parameters were identified and introduced in a numerical scheme to compute bone stresses for loading histories with moderate deformations.
