Hello All,
I have a problem. I made a very simple simulation to test the 1D element performances. One has been built with beam elements, other has been built with truss elements. All other properties are the same. Both are under tensile loading, nlgeam is on since the material is nonlinear...
Hello All,
I want to use no compression 1d elements in abaqus explicit (elements like nastran gap elements). I used hyperelastic material with negative strain and force but it gave unrealistic results.
Basically, I want to model model a mass spring system. The spring has nonlinear stiffness...
Hello Everyone,
I have modelled a net with following parameters:
Net elements: Truss(T3D2) - hyperleastic
Frame: Beam(B31) - linear elastic
BC: constraint: DispXYZ=0 at two side of the frames
load: 1G gravity which is normal to net
Step: General static, nlgeom=on
It is a pretty straight...
Dear All,
I am doing a web catch analysis using abaqus dynamic explicit. An object with initial speed of ~50000mm/s is cought by a web which is built with B31 elements. B31 elements has hyperelastic properties. Contact between object and web was defined as general contact. Analysis duration is...
Hello All,
I'm new to Nastran and have a question related to SOL 129 solver.
I have a model which is running perfectly in SOL 109 (linear transient) solver. For some reason I needed to use gap elements for contact problem, thus I switched to SOL129. However gap elements are not working...
