Hi, I am having some trouble with the cohesive elements... I am using the cohesive elements to simulate the crack growth on an aluminium thin panel using 3D elements. I have a crack in the middle of the panel meshed with 0.2 mm cohesive elements that must not be damaged under the load that I am...

Hi, I have to study a crack growth to obtain the residual strength curve. My model has a cohesive elements zone with a stress-displacement law. I am able to run a static analysis and obtain the stresses at the crack tip. However I do not know if there is a way to add load automatically until...

I finally found the difference, when importing the model Abaqus creates S4R elements instead of S4 elements.

Hi, I am working with a Nastran model but I need to convert the model into an Abaqus model using the Abaqus's Nastran translator. The problem is that the results are not good, I have a huge difference between the displacements in the Nastran model and the Abaqus model. I do not know if there...

Hi, I am working with a model and I need to refine the mesh locally. This is a shell s8r elements mesh, and I do not know what is the best technique to achieve this mesh refinement. I have tried using the MPC QUADRATIC but I do not get good results so I am trying to do the local refinement using...

I am having some problems with these tool. I am doing this coupling with S4R and C3D20 element, and I have problems especially when I try to get the nodal force acting in the C3D20 element. The model is a square plate with a 3d model in the center, with two shell edge traction loads. The shell...

I think that is excatly what i was looking for. Thanks.

Hi, I need to modelize one shell with one three-dimensional elastic submodel in the middle of the shell. The fact is that I do not really know how to connect the mesh correctly, having the same load in the 3d submodel that the load that would be in the shell. Thanks
