Greeting to all iMechanicians,

Read Prof Alistair Borthwick's (University College Cork, Ireland) March 2012 editorial for ICE journal Engineering and Computational Mechanics for free here. Link http://www.icevirtuallibrary.com/content/article/10.1680/eacm.2012.165.1.1

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
