software of interest to mechanicians
I have a question about deformation gradient in VUMAT.
When I use one element, Vumat works well and there is no any problem. Initially, only the diagonal part of deformation gradient is one, the others are zero. However, the problem is when several elements are considered, all the components of deformaiton gradient are equal to one at very beginning.
hi, i want yield stress and plastic strain data for aluminium and epoxy resin.actually i m doing project on composites.....
I guess it is about time some one from the Cornell Fracture Group got on this site to try help answer questions related to the CFG software or other fracture mechanics related questions. We do try to answer questions sent to us via email, but sometimes a forum like this would be best and we do appreciate other users input, feedback, and answers.
hi...i am doing drilling simulation on abaqus....
it consist of two parts...a tool and a blank....
now when i am running analysis...tool touches the blank and goes back.
i checked material data...density,elasticity...and i used surface to surface interaction with penalty as interaction property....
can any one tell me ...how to perform this....
Dear all,
I must apply a user defined heat flux to ABAQUS for getting thermal profile in defferent nodes and elements. How can I apply this user defined heat flux to AVAQUS and how can I write this user defined heat flux for ABAQUS?

This days, I am working on the dynamics analysis using the Abaqus. the implicit dynamic integration method in abaqus is HHT-alpha. I found that a very strange parameter about the method is the half-step residual tolerance . I don't know the parameter is whether important or not and how to determine it.
thank you very much :)
Does anyone can help me on spooles package's iterative method ?
Dear everyone :
I need your help !
I am using spooles , and I have successfully
use it in direct methods which is in directory
/misc/drivers , and I have run into problems when
I use the code in /Iter/drivers , for the demos in it
, I have run successfully , but I want to use the same
matrix of A and b as in direct method when I do in direct,
in fact , I am use a fortran code for main program , I
only to take use of spooles as a subroutine , to solve Ax=b for
me, the code iter.c in Iter/drivers , is a main c program , and I want to
change it as a subroutine for my fortran main program .
and I don't know how to change it to a suitable code . because in the
