I am implementing a uel user subroutine in ABAQUS. This uel is for modeling contact in X-FEM framework. Thus, it's a nonlinear problem and I need to store some solution dependent variables during each iteration. I know I can store SDVs in SVARS. But this vector will update at the end of each step, and not during iterations. Anybody knows about this problem?

I really appreciate if anybody can help me with this.

Thanks

modelling of crack propogation

woven composite

Hi everybody,

I am anurag working on damage mechanics of 2x2 twill woven composite, i will conduct the carbon/epoxy laminates under various regimes of service loas (quasi static loading, low velocity impact, fatugue, post impact) and will also model crack propogation of the same using XFEM.I have studied FEM at graduate level.

Initially i will calculate mechanical properties of woven composite using unit cell method by applying homogenization process.

Combining UMAT with XFEM

Submitted by Panos Efthymiadis on Tue, 05/31/2011 - 10:12

Hi all,

I 'd like to ask whether anyone has applied XFEM for a user-material (UMAT). What is the process to do that? Could anyone provide some advice, documentation or guidelines?

All the best,

Panos

p.s. I 've heard that a UEL code is needed to couple XFEM with UMAT.

Enriched Finite Element Methods

Dear Colleagues,

I would like to invite you to submit an abstract to the XFEM session of the
SES 2011 Annual Technical Meeting of the Society of Engineering Sciences which will be held this October 12-14, 2011, at Northwestern University in Evanston, Illinois.

The mini-symposium is seeking abstracts in the area(s) of enriched finite element methods, the extended finite element method and other related numerical methods. We welcome fundamental and applied abstracts relevant to this area.
