Thank you FEA way , it worked I changed I_A to 20 . damage stabilization and contact property did not help. I did not know how to turn on discontinuous analysis. also I think in CAE 2019 dassault removed XFEM crack growth interaction. The result is not what I expected but maybe it could be...

I have created XFEM crack on cell partition I followed Abaqus documentation, but the problem is as soon as the crack initiate the iteration fail to converge. I have lowered minimum iteration step but it didn't solve the problem. I think that I need to create XFEM crack growth interaction but I...

Solved the problem ,I made a new experimental test.

I have tried quadratic hexahedral element ( C3D20R ) using implicit analyses , now my results are excellent for specimen tensile test as shown in the pic here , I think my problem was I have to increase the number of elements through the sheet thickness or use a better element like ( C3D20R )...

NLGEOM is on , no I did not try full integration second order element , yes I have checked with implicit analyses it was very good in elastic region but at high strain before failure the analyses stops ( due to high non-linearity ). sorry I did not explain my self , when I say results I means...

Hello I am trying to simulate uniaxial tensile test on 50mm gauge length stainless steel specimen on Abaqus. My problem is only in the elastic region it does not match experimental results, and the plastic region is 99% matching my experimental results. My model is explicit with Hex 8 node...

I am using abaqus cae 2017 , the model step is dynamic Explicit.

Hi guys I am trying to simulate a 3mm diameter spot weld between two 1mm sheets. I want the weld to fail at 3000 Newton shear force ( interfacial failure ). I have tried to simulate it by using discrete fastener but the problem is I can not make it fail at 3000 Newton , the connector type I...

Hello guys I am trying to simulate a tensile test for 304 stainless steel flat specimen 50mm gauge length in ABAQUS. I have already done it experimentally in the lab using universal testing machine and now I have stress Vs. strain graph. The problem now is I need to find fracture strain Vs...
