ABAQUS offers the possibility to model non-linear isotropic materials as well as linear anisotropic materials. However, it is not possible to use these two capabilities at the same time in order to model anisotropic hyperelastic materials. Gurvich proposed to model such materials by means of the linear superposition of two fictitious materials: a linear anisotropic, and a hyperelastic isotropic...

Based upon the fundamental solution to a single straight dislocation segment, a complete set of exact closed-form solutions is presented in a unified manner for elastic displacements and strains due to general polygonal dislocations in a transversely isotropic half-space. These solutions are systematically composed of two parts: one representing the solution in an infinite transversely isotropi...

Osteogenesis imperfecta (OI) is a heritable bone fragility disorder characterized by skeletal deformity and “brittle” bones. This fragility is believed to stem from a combination of bone mass deficiency and compromised bone material properties [1-3]. Poor bone quality poses major orthopaedic and rehabilitation challenges. Risk of fracture is a major consideration when prescribing activity restr...

This document contains additional material for the submission Procedural Isotropic Stochastic Textures by Example. Additional Results Figure 1 and figure 2 are extended versions of the corresponding figures in the paper. These figures also contain context photographs and additional results. In the paper we state that the method of Heeger and Bergen and our method achieve a similar synthesis qua...

Of the plethora of work performed analyzing skeletal muscle tissue, relatively little has been done in the examination of its passive material properties. Previous studies of the passive properties of skeletal muscle have been primarily performed along the longitudinal material direction. In order to ensure the accuracy of the predictions of computational models of skeletal muscles, a better un...

in this article, a transversely isotropic linear elastic half-space with depth wise isotropy axis of material containing a cylindrical cavity of finite length is considered to be under the effect of an arbitrary torsion force applied on the wall of the cavity. to this end, the equation of equilibrium has been written in a cylindrical coordinate system, by dividing the involved domain to two reg...

In this article, a magneto-mechanical model is coupled with an energetic approach of hysteresis. The proposed modification of the parameter related to the coercive field can model the local enlargement of the hysteresis loop under compression. The proposed model is validated by comparison with measurement at different levels of stress.

6 Patient-specific high order finite-element (FE) models of human femurs based on quantitative computer tomography (QCT) with inhomogeneous orthotropic and isotropic material properties are addressed. The point-wise orthotropic properties are determined by a micromechanics (MM) based approach in conjunction with experimental observations at the osteon level, and two methods for determining the ...

Most of the observational claims in cosmology are based on the assumption that the universe is isotropic and homogeneous so they essentially test different types of Friedmann models. This also refers to recent observations of supernovae Ia, which, within the framework of Friedmann cosmologies give strong support to negative pressure matter and also weaken the age conflict. In this essay we drop...
