A Logarithmic Strain Decomposition for Modeling of Trabecular Bone Subjected to Large Compressive Strains
Original language description
The geometrical nonlinearities may play an important role in the modeling of osteoporotic trabecular bone. The magnitude of geometrically nonlinear effects depends on the bone volume fraction and becomes more important for low-density bone. Development of a fully nonlinear model of trabecular bone (including material as well as geometrical nonlinearity) can be useful for description and exploration of the fracture properties of low-density trabecular bone. In this contribution we will explore an extension of the small-strain model for trabecular bone combining anisotropic elasticity and anisotropic plasticity with isotropic damage, to the large strain range. The extension to the large-strain range is based on the additive decomposition of the logarithmic strain into elastic and plastic parts. An efficient implementation into an object-oriented finite element platform will be presented, the algorithmic aspects will be discussed and application of the model will be illustrated by an exam
