Stent/Artery contact Abaqus Explicit

Submitted by Slimjimmy on

Hi Everybody.



I'm modelling Nitinol stent crimp and expansion
into an idealised artery in Abaqus/Explicit. I am having numerous
problems with the ratio of kinetic energy to internal energy with the
analysis. I was hoping somebody may provide me with some insight on
this.



I am modelling the crimp stage using a C3D8 elements for
the stent and have defined a surface section for the crimper surface. I
am using kinetic contact and surface to node contact (surface to surface

tsai wu failure criteria in ANSYS

Submitted by yashidanadir on
research

dear friends, i want to know how to get the tsai -wu failure criteria for orthotropic material in ANSYS.after modelling and giving the material properties ,should i give anything special to activate this option ,or will i get automatically this  criteria for all the elements from the output file itself.

please help me as my research work couldnt able to proceed.

Modelling isotropic hardening

Hi

 

I am having difficulty with modelling isotropic hardening for sheet metal material in a simple spreadsheet or MathCAD program.

 

I can model the initial yield condition using an appropriate (plane stress) yield criterion. I have also fitted a hardening law to the experimental data for uniaxial tension. I am having difficulty with the effective stress-strain relations and how this relates back to yield surface expansion. 

 

Has anyone modelled experimental data in this way?

Hello everyone,

I am working on a project related to helping the everyday researcher do his/her programming easier and faster.

I have done a fair amount of research work at OSU and have gotten a feel for the way they program on a daily basis, but realize that it could be and probably is drastically different on different parts of the planet. As such, I am here to ask the following questions (really, any opinion helps, so feel free to respond with whatever you want):
