Hi everyone, Could you help me understand the phenomema that I describe below ? I conducted a non-linear analysis with activating LGDISP. After comparing the results with and without LGDISP, I found that there is a big difference in displacement. If I don't activate LGDISP, the displacement of model is very large. Otherwises, the displacement becomes small with LGDISP. I don't understand this phenomena. Note : In my model, I have plastic material so with small young's modulus , but just linear comportement is taken into account (I don't have informations on parameters for determining its non-linear comportement). I implemented non-linear analysis because of contact phenomena. Thanks for your helps.
Hi, I have a model of a breast that should be deformed between two plates. I have tried various variations using the PCONT card, CNTSTB, and EXPERTNL with CNTSTB and I still cannot get the model to produce results. I have tried increasing the NINC card as well to not avail. The top plate will move but it is not interacting with the breast to have it spread across the bottom plate. Any help would be greatly appreciated.
