Yes, thanks for the information. Is it possible to use the *IMPERFECTION command to input imperfection into the dynamic explicit analysis as follow:
*IMPERFECTION, FILE=Job-0_Initial_Imperfection, STEP=1
1,1
** STEP: Step-2
**
*Step, name=Step-2, nlgeom=YES
*Dynamic, Explicit
, 10.
etc
etc
etc...
JSDaniel I was able to figure out and I did an initial imperfection in the middle of the plate and ran a static, riks and was able to get a load displacement curve. Now I want to match up this using a dynamic explicit analysis. Can you please tell me how to put the compressive force(load...
JSDaniel I ran a (static,riks) with lateral distributed load and compression force but the reaction force(Compressive force Ny) is larger than the Ncr given by the linear perturbation. Shouldn't this analysis be aborted when reaction force reaches Ncr for the first buckling load
Hi guys,
I hope you can help with this problem. I have modeled a thin rectangular plate(Kirchhoff plate)and chosen S4R5 shell elements for my mesh. I did a linear perturbation and the simply-supported plate which gives me the correct eigenvalue and eigenshapes comparing with analytical results...
