hai,

my project is analysis of functionally graded plates for thermal loads using matlab in this regard i need certain basepaper regarding "bending,buckling and vibrational analysis of composite laminates(cross-ply & angle-ply)subjected to only thermal loads(i,e temperature increment) either constant or linear change using different theories as classical laminate plate theory(CLPT),first order shear deformation theory(FSDT) and zeroth-order shear deformation theory(ZSDT)"

Hello everyone,

 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

Dear all,

Can anyone tell what kind of value of power i need to use for a PU glue? At the moment i am using the Benzeggagh-Kenane (BK) criteria.

Or will it be better to use the power-law mixed mode criteria for a glued in rod in timber?

I look forward to receiving your answer,

Ronald

 INSAVALOR, the subsidiary of industrial development and further education of INSA Lyon and further education service of Grenoble INP offer throughout the year a high-level seminars based on the results of research laboratories schools.

These seminars in English or/and in French (with a duration of 2 to 4 days) are designed for global companies that wish to promote the development of skills of their executives, experts, specialists, researchers. 

Public Profile

Mini-Symposium on "Developments in Finite Element and Meshless Formulations Applied to Metal Forming Problems" (MS124), within the ECCOMAS 2012 International Conference, September 10-14, Vienna, Austria 

Mini-Symposium description

Numerical simulation analyses of metal forming processes involve a high level of complexity, from both fundamental and industrial application standpoints, requiring robust and comprehensive technology in order to achieve realistic solutions.

At Oxford University we are seeking to appoint a post doctoral Research Assistant to work on the modelling of cavity nucleation and growth in the heat affected zone of a welded component operating in the creep regime. A detailed advertisement and further particulars about the post can be found in the attached files.

Hi all,

I am using FEAP 8.2 in my university, and have to write a user material routine, but there is no clear guideline/example about which files to modify for this purpose. Sorry to say, the programmer's manual is very short, and very little detail is there.

The old tutorials/examples based on FEAP (7.x) are no longer helpful because the FEAP 8.2, 8.3 source code has changed considerably (atlease the files in user folder), hence the novice can get mad after trying for many weeks to figure out the way for doing this.
