On the Compatibility Equations of Nonlinear and Linear Elasticity in the Presence of Boundary Conditions

Submitted by arash_yavari on
research

We use Hodge-type orthogonal decompositions for studying the compatibility equations of the displacement gradient and the linear strain with prescribed boundary displacements. We show that the displacement gradient is compatible if and only if for any equilibrated virtual first-Piola Kirchhoff stress tensor field, the virtual work done by the displacement gradient is equal to the virtual work done by the prescribed boundary displacements. This condition is very similar to the classical compatibility equations for the linear strain.

Dear Colleagues,

We would like to invite you to participate in the minisymposium “Nonlocal Theories and Multiscale Methods for Complex Material Behavior” that we are organizing at the 12th World Congress on Computational Mechanics (WCCM XII) to be held on July 24-29, 2016 in Seoul, Korea, jointly with the 6th Asia-Pacific Congress on Computational Mechanics (APCOM VI).

We performed a comprehensive study of a large class of Implicit and Explicit integration algorithms for Elastic-Plastic behaviors in Finite Element Analysis (FEA) developed in UMAT and VUMAT for ABAQUS and presented various unique results. We also showed detailed integration algorithms for both Associated and Non-Associated Flow Rules with mixed isotropic and kimenatic hardening with expandable number of internal variables (damage and etc).

refine brick / voxel mesh

Submitted by Frank Notts on
research

Hello,

Discretising geometries with a brick (voxel) mesh of constant element size is very simple and quick.  However, sometimes there are locally small features which would benefit from a more refined discretisation... In my case, the geometry (a textile reinforcement) is complex and tet meshes get very large very quickly – and are slow to generate. Hence, bricks are a simple way forward.

Here are some geometry examples: http://texgen.sourceforge.net/index.php/Main_Page
