Geometric nonlinear thermoelasticity and the time evolution of thermal stresses
In this paper we formulate a geometric theory of nonlinear thermoelasticity that can be used to calculate the time evolution of the temperature and thermal stress fields in a nonlinear elastic body. In particular, this formulation can be used to calculate residual thermal stresses. In this theory the material manifold (natural stress-free configuration of the body) is a Riemannian manifold with a temperature-dependent metric. Evolution of the geometry of the material manifold is governed by a generalized heat equation.

Abaqus explicit-Unexpected output results

Hello everyone,
I made simple cantilever model in Abaqus/Explicit. For concrete I have used Concrete damaged plasticity model and for reinforcement I have tried two models (one with Truss and second with Beam elements). I have assigned displacement as BC (Smooth amplitude) in Reference Point at the end of the beam, and I have coupled RP with the end of the beam. For concrete beam I have used C3D8R elements.
For history output I have requested Reaction force in RP and energies for whole model.
But results I am getting aren't expected.
Rubber Adhesion Behaviour
Dear everyone
My project is about the adhesional friction between rubber and a rigid surface. In this case I have modeled a block of rubber which is sliding on a real rough rigid surface in ABAQUS.

matlab code to create cohesive elements (or UMAT) in any 2D mesh
To use cohesive elements, normally user can add a layer of elements between neighbouring node pairs. This matlab code can help you to process that especially your FE mesh is irregular. The code, the initial .inp file and corresponding out put files are attached for a better illustration. The new generated cohesive elements won't cause any trouble in the element number. Also you can apply this code to generate new UMAT elements in mesh.
