Can anyone help to establish the contact state after an importation from abaqus/Standard to abaqus/Explicit?

Hello everyone, I performenced a 4 point bending calculation in Abaqus/Standard, and then I imported the resultats to Abaqus/Explicit to do a dynamic job. Due to the difference of the contact...

Is it possible to co-utilize XFEM and cohesive elements in Abaqus?

I have a question about the feasibility concerning the co-utilization of XFEM and cohesive elements in Abaqus. In fact, in the documentation, they did mention that XFEM could be simultaneously...

Is there a cohesive zone model that is able to simulate the fast fracture propagation but with a quasi-static load?

I'm now trying to simulate the fast fracture on my thin brittle plate subjected to a quasi-static bending load. Is there a cohesive zone model that is able to simulate the fast fracture...

Can anyone help with grain boundary simulated by cohesive surface in Abaqus?

I'm doing a simulation for a thin plate polycrystalline subjected in pure bending, and I consider the grain boundaries by the surface interaction using the cohesive surface behaviour in Abaqus....

Does anyone have information about Abaqus XFEM based on the LEFM-initiation of crack?

Does anyone know about the Abaqus XFEM based on Linear Elastic Fracture Mechanics? The question is about how the fissure initiates under this finite element analysis framework. It's not like the...

What is wrong with the STRESS values in UDMGINI user subroutine in Abaqus?

I wrote a subroutine UDMGINI to define a damage initiation criterion, but I found that the variables of stress were very strange. I kept track of stress (NTENS) using the state variables STATEV,...

Can anyone help with simulation using XFEM in Abaqus?

I am trying to simulate brittle crack without initial crack using Abaqus XFEM. Specifically, I make a simulation of the 4 point bending (contact problem) on a very thin orthotropic plate...

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.
