ShellDKGT

Good Afternoon to all OpenSEES community. I have a question related with ShellDKGT element. I have done several tests comparing ShellMITC4 and ShellDKGT elements using LayeredShell sections with J2Plasticity material and I have similar results in Displacements Field and Tension Fields. The problem a...

PlateFiber Recorder

Good afternoon to all OpenSees Community. I have a question related with stress-strain recorders when using Shell elements and PlateFiber Section. I have questions using these commands: 1. recorder Element -file file_name -time -ele elem_number material gauss_point fiber layer stress 2. recorder Ele...

Re: J2Plasticity material

Good morning. The model is a rectangular simply suported plate in its four edges with a central load applied in positive z direction. I have done the same model with ANSYS using a von Mises yield criterium because I wanted to compare it with J2Plasticity model. I want a Bi-Linear material law so I h...

J2Plasticity material

Good afternoon to all the OpenSees Community. I have a doubt about J2Plasticity nDMaterial. I have running simulations using this material with shell elements and I have problems when I reach plastic behaviour. I have not this problems with others nDMaterial like Drucker-Prager. I have seen the sour...

Shell Elasto-Plastic Analysis

I am modeling a squared steel plate supported in its four corners with an incremental constant load applied in its center in a perpendicular direction. I have tested several shell elements and the material is J2Plasticity with a PlateFiber Section. It works fine for the elastic range using a Linear ...

Re: Which shell element is capable for elasto-plastic analysis?

I am modeling a steel plate with shell elements and J2Plasticity material and I still have the same problem. It is corrected for sure?
