This chapter summarizes our works on surface wrinkling of elastic thin films, taking a kinetics approach as a physical pathway to both ordered and disordered wrinkle patterns.

I am graduated from Physics departmentOran
University, Algeria in june 2000. Then I complete my MSc in the field of
material science from the Oran University, Algeria in November 2004. Recently I
complete Ph.D. thesis at the university of Duisburg-EssenUniversity germany,
thermodynamic department in July 2011 . In my PhD, I deal with the synthesis and characterization of the
functional doped metal oxides.

Dear All,

I have the problem. i created very simple example with two elements. To one element i prescribed the behaviour Mat1, to another element Mat2. I tried to use two different UMATS for this two elements.

I created Subroutine Myname.f, in which i use CMNAME if (CNMAME.EQ.'MAT1) THEN

CALl UMAT_1()

ELSE IF (CMNAME.EQ.'MAT2) THEN

CALL UMAT_2()

END IF

Then i put two UMATS in the same SUBROUTINES ,

But as a result the program gives MISTAKE , it says that The UMAT doesn't exist

What is the mistake?

Dear Colleagues



This is a gentle reminder that the final date for submission of abstracts to the



11th Global Congress on Manufacturing and Management GCMM 2012



has been extended to 31 March 2012.



You are cordially invited to submit a paper and be a part of this event.

Dear all (and Prof. Ciavarella, if you can see this),

I am looking for an equivalent indentation modulus for orthotropic composite materials in a contact problem. Does anybody has any reference or equation to get the value?

2012 Northeast Society for Experimental Mechanics (SEM) Graduate Student Symposium is being arranged in University of Maryland, College Park. Please feel free to express interest. Any graduate student working in the Experimental Mechanics area is welcome to present their research work. Flyer attached.

We are organizing a topic on “Fatigue Failure in Engineering Materials and Structures” in the in the upcoming ASME 2012 International Mechanical Engineering Congress & Exposition. We strongly encourage researchers to submit abstract(s) to this topic and attend the conference. You can locate the topic under the Technical Track Section 9 “Mechanics of Structures and Fluids” and Sub-Section 9-29. The conference will be held from November 9 to15, 2012 at the Hilton Americas and the George R. Brown Convention Center, Houston, Texas.
