Hello everyone, How to define interior self contact for one soft foam or rubber solid? In my simulation, I found some elements penetrate other elements in the same solid part due to large deformation. How to correct this problem? Best Wishes Roy
hello, I want find the stress on rubber component when in fixed at bottom and apply load 4 N on it. What card image i should go in material and loads. Please explain me procedure how to conduct this analysis. Whether i can do this analysis in optistruct Thank You
Dear colleagues, I need your help to find the Prony series coefficients using DMA frequency sweep, so I can use them in a FEA study. The data I got from the test are 50 points for Loss modulus, storage modulus, tan delta, strain and amplitude Vs. Frequency. I need to calculate either relative moduli Vs. relaxation time, or shear modulus Vs. time, or Bulk modulus Vs. time. Your advice will be highly appreciated Best regards, Gerges Youssef
I am simulating a rubber component where rubber has a self - contact as it compresses, but i can see through animations that elements are intersecting and penetrating. I have defined type 19 self -contact (with Istf=4 and inacti 6 and igap =1) by using surf cards via components. and used mat 42 as material card and Isolid 24 as formulation. with material property. The model is in volume cavity and can only displaces in gap between it and load is applied horizontally by displacing a rigid shell along outerbody in horizontal direction and rigid element with internal nodes of rubber is fixed in space. Cut -section displacement <2mm (gap is 2mm) and element start to deform at before gap reduction element distortion and time step is reducing .there is penetrations and intersection between elements despite self-contact what should be contact parameters or any other input to avoid such behaviour?
