Over 100 years ago, Wolff hypothesized that cancellous bone altered both its apparent density and trabecular orientation in response to mechanical loads. A mathematical counterpart of this principle is derived by adding a remodeling rule for the rate

This paper is concerned with the continuum formulation of a fully coupled thermomechanical constitutive model for highly deformable bodies with viscous dissipation. The threedimensional material law is applicable to the thermomechanical characterizat

This paper presents a detailed comparison of two implicit time integration schemes for a simple non-linear Hamiltonian system with symmetry: the motion of a particle in a central force field. The goal is to establish analytical and numerical results

The present paper addresses modeling and numerical description of stress-induced phase transformations in solids. The study is developed in the setting of a generalized neo-Hookean elastic material under anti-plane deformations. It is assumed that th

This paper examines the long-term dissipativity and unconditional non-linear stability of time integration algorithms for the incompressible MHD equations. The results apply as a particular case to the uncoupled incompressible Navier-Stokes equations

A framework for damage mechanics of brittle solids is presented and exploited in the design and numerical implementation of an anisotropic model for the tensile failure of concrete. The key feature exploited in the analysis is the hypothesis of maxim

We examine a new Galerkin method with scaled bubble functions which replicates the exact artificial diffusion methods in the case of 1-D scalar advection-diffusion and that leads to non-oscillatory solutions as the streamline upwinding algorithms for

The long-term dynamic response of non-linear geometrically exact rods under-going finite extension, shear and bending, accompanied by large overall motions, is addressed in detail. The central objective is the design of unconditionally stable time-st
