Large Deformation - Definition of total work energy density
Forums
Choose a channel featured in the header of iMechanica
Like we have the elastic strain energy density for small deformations defined as 0.5* σ :e .
Is the equation PK2:E valid for the total work energy density for elastoplastic regimes ? If not, what would be a valid equation for total energy density ?
How can we decompose total work density into elastic work and plastic work densities for a large deformation case.
Where,
PK2 is the second piola kirchoff stress tensor
E is the Green-Lagrange strain tensor
Thanks,

Plane_Stress, Plane_Strain and 3D - Simple doubt..
Choose a channel featured in the header of iMechanica
Hello everybody,
UPDATE : Question can be deemed as closed.. :)
I have a very simple doubt in 3D model simplification. I believe plane stress and plane strain conditions are the two extreme states to simplify a 3D model to 2D case.
Transfroming applied tractions into statically equivalent nodal force BC

Hello,
I am trying to produce results for problems with analytical solution to validate my FE code. One of the problmes is the classical plate with a hole configuration with tractions applied at boundaries. However, presently, I can only impose BC in terms of nodal forces and displacements. Therefore I must transform the applied stress in statically equivalent nodal forces.

Pressure Difference Calculation in ABAQUS
Hi everyone,
I am working on ABAQUS to simulate Pipeline Inspection Gauge (PIG) movement in a pipeline via CEL technique. I am unable to find how to calculate Pressure Difference in the pipeline using Abaqus.
If anyone of you can guide me through it.
Regards,
MD Aftab
