software of interest to mechanicians
Hi all
I am using Hypermesh for modelling a simulation model for automtorive structure.
But I dont understand which is better for my usage.
I need to make 1.Geometry cleanup 2.Mesh (2D & 3D) 3.also setup for some type of analysis (ex: strength,Crash)
Which will be beter for above operations.
Hi,
I am trying to mesh the hollow sphere attachged using structured BRICK-8 elements. It turns out in order to have a structured mesh, I have to have 2 partitions such that four quadrants be generated.
What I only need from ABAQUS is the element connectivity. I do not need to solve any problem.
Hi everyone,
I am new to ABAQUS software and recently i was trying to implement compressible neo-Hookean material in ABAQUS and for me it is a very difficult task. There are already codes available for the nearly incompressible neo-Hookean material. Since ABAQUS is a widely used software, i was wondering whether there are any database avaible consisting different codes that we can access. I am desperately looking for a subroutine for compressible neo-Hookean material. Can someone please help me or give me some direction. Thanks a lot !
I want to set the contact pressure as a input in the routine but I don't know if there is a subroutine allows reading the contact pressure.
Thanks a lot for answering the question!!!

Hello everyone, I am using ABAQUS to study the tangential behavior (friction) at the interface between rock-machine. I know tangential behaivour simualtion is key for my model, I read the manual, but still have some puzzels, hoping you could help me, much appreciated in advance!
1. what's the difference among mechanical constraint formulation of penalty contact method (another is kinetic), friction formulation of penalty for tangential behavior, and constraint enforcement method of penalty for normal behavior. the explanation in manual seems ambiguous for me.
Hi,
I am beginner in abaqus and I want to write a VUMAT for VIB method to simulate fracture, while writing VUMAT i encountered following problems
1) For 2D plane stress problem how to calculate strainInc(*,3). It is increment for that step or value of strain till that step?
2) What is effect of that defination on answer I am getting?
Greetings,
I wrote the following subroutine to extract nodal stress values. It perfectly writes down the nodal stresses in MSC.Marc installed for Linux; however, when I try to implement this subroutine in MSC.Marc installed for Windows using intel(R) Visual Fortran compiler, error "forrt1: severe <157>: Program Exception - access violation" occurs.
The subroutine is:
subroutine impd(lnode,dd,td,xord,stnod,f,v,a)
