finite element analysis

Dear ALL,

Does anyone here has an experience carry out  FE analysis for a part[bracket] which was deformed plastically during cyclic loading test.

I'm now working to resolve this issue when a bracket was fail to withstand the constant loading of 500N during cyclic test. It was reported fail at ~3800 cycles which was less than target.

Rgds.

Hi

I'm facing problem while writing a script for a parametric study.

After changing the each parameter the model changes and and the loaction of the interested element changes based on those parameters.

Also the element number changes.

Is there any command in python script to choose the elements based on the location ? 

Thank you in advance

I have a one dimensional bar with a triangular pulse given at one end for 2 microseconds. The boundary conditions are free-free.I am having two cases. One in which the deformation is local (Hooke's law) and other in which the deformation is dependent on a kernel of radius r (say 5* element length).I find that the wave speed is higher when the deformation is non-local as compared to local deformation case. Is this correct? Is there a way to verify the solution?

It is a long-standing goal in metallurgy to enhance the strength of materials without sacrificing ductility. In a recent article in Nature Communications, we reported an effective way to evade the strength-ductility trade-off dilemma in twin-induced plasticity steel.

Dear All, 

We (the NanoBIO Node at Illinois ) have a preliminary release of an online finite element analysis of nanoindentation (indentation) tool using FEAP . 

This preliminary release is limited to linear elastic material, axisymmetric geometry, spherical rigid indenter, and various boundary conditions. 

I did a 2D beam bending problem with CST and Q4 element, respectively. CST gives better accuracy. Is it due to the shear locking effect with Q4?
