Thank you so much, you helped me to narrow down the issue I thought about memory, parallelization .. I solved it! you are right it is in the subroutine, I found a mistake in the interface when I copied it from abaqus documentation I forgot to change strain by stress: field(nblock, nfieldv)...

Hi all, I am working on a damage model (ductile damage: fracture strain as function of Triax and Lode parameter), and I need to change the fracture energy for the damage evolution as a fuction of triaxiality for that I wrote a VUSDFLD subroutine I tested the fortran code on for 1 element...

Hello, I am trying to calculate the J integral using Digital image correlation in SENB steel specimen, there are some papers discussing the method but not in details. my problem is that I have no idea how to create a path and extract the results (displacement and strain filed for the...

Elastic-plastic for both, to capture the plastic behavior I used true stress strain curve from the tensile test.

The geometry is exactly the same, the only difference is the crack length. I tried to change the material in one of the model with the closes crack length that I need but still have the same issue. one of the material is highly ductile, the other is more brittle I am afraid that the model is...

Hi everyone, I am modelling a 3 point bending test on a SENB specimen with a fatigue precrack using Abaqus/standard. For the FEM model I've used 3D solid to model the specimen and discrete rigid body to model the punch and roller, as for the crack I've used contour integral. I applied a...

Thank you for your reply. I didn't use the material calibration tool, I just transformed the engineering stress strain from the tensile test to true stress strain using the equations in excel and implemented in abaqus.

Hi all, I am modelling a steel Double edge notched tensile (dent) specimen in abaqus/implicit. I used for the model isotropic hardening, the material properties are acquired from standard uni-axial tensile experiment, quad elements with reduced integration are used and a very refined mesh near...
