I would like to combine Extended Finite Element Method (XFEM) with cohesive behavior in Abaqus to model bulk damage as well as interlaminar damage in a material.
Section 10.6.1 of the Abaqus 6.9 Analysis Users Manual says that XFEM "can be simultaneously used with the surface-based cohesive behavior approach or the Virtual Crack Closure Technique, which are best suited for modeling interfacial delamination."
Hi, i need help modeling sandwich structure in ANSYS 12.1, i have found some materials online on how to do it? I have tried the basic steps. got some results, but now how do i validate that. I have experimental data for three point bending. But i want to make sure that what i am doing in ANSYS APDL is darn right.
3 layers 45/0/45
thickness 0.1/0.365748/0.1 (inch)
material i am using right now are carbon fiber and foam DH100
properties of each layer have been assumed to be isotropic
I'm trying to investigate the effect of multiple support excitation (spatially varying ground motion) on seismic response of an arch dam using ADINA, so i need to apply different acceleration (and velocity and displacement) time histories on every node on structure-foundation interface.
I've to model a gearbox in the transitory (acceleration) and in the
stationary (constant speed) running: i'm not sure abut the kind of step
I'm gonna find contact pressure and stress in both case.
I need some help with MIMICS software please. I have a CT scan images for the whole body and i need to create 3D object for the shoulder model to each part Humerus and Scapula and then perform some measurments then Export it to ABAQUS. Does any one have any idea. Please help.
I would like to know whether there's any method to submit a
number of Abaqus implicit jobs at once (like letting it to run whole
night without any attention)? Also is there any way to run those jobs
without opening Abaqus CAE (like in the command prompt) in a computer
with Windows vista? I have modeled everything in CAE.
We tried to simulate simple shear using ABAQUS and compared it with the analytical solution. To our surprise, even though the equivalent stress and strain matched perfectly, the component stress and strain had a large deviation between the semi analytical and ABAQUS methods. The zero components in the analytical model were calculated to be non-zero in the results of ABAQUS. This paradox could not be understood clearly as whether it is a case of software deficiency or conceptual error. A COMPLETE ANALYSIS OF THE PROBLEM IS ATTACHED AS A REPORT.
I have a problem with applying periodic boundary condition. I have used *EQUATION in constraints for opposite nodes and surfaces. But I still have some problem with that for sure I making some simple mistake. If anyone could look at my model and find problem. Abaqus version 6.9-1 .
Thanks a lot.
All, I am conducting a survey and your response would be very much appreciated. The purpose of the survey is to gather data that will help the developers of open source software improve the success of their projects. All replies received before midnight Sunday 26th September will be entered into a draw for a £30 Amazon gift voucher.
