Conformability of a Thin Elastic Membrane Laminated on a Soft Substrate With Slightly Wavy Surface

Liu Wang, Nanshu Lu*

Dear iMechanicas,

I need advices from experts regarding choosing a proper interalaminar damage model for the implementation into the theory of plates and shells. I am going to apply a failure criterion which is straight forward but concerning the degradation procedure of material properties I may need some suggestions.

Best regards,

A Senior Researcher/Researcher position is available at the Technical University of Denmark (DTU), at the Department of Wind Energy in the Section of Composites and Materials Mechanics. The Section consists of about 30 people and has modern laboratories for manufacturing and mechanical testing of composite materials. Research is conducted in research projects usually with external national or international collaboration. The research focusses on composites materials consisting of long, aligned fibres in a polymer matrix for use in wind turbine blades. 

Applications are sought for four Post-Doctoral Research Associates to join a very active research group at Cardiff University, UK (School of Engineering).  Based in Cardiff, there will be frequent interactions with the University of California, San Diego as well as major aerospace companies in the UK. The research will formulate and develop numerical methods for mulitiscale and multiphysics design optimisation using level set topology optimization.

One or more of research experience in the following areas are required.

Hi all, 

     I want to model mode II composite delamination incorporating frictional effects. I found papers by Alfano and Sacco (2006) and few others also. My question is that to model such a situation are :

1) should I incorporate plasticity or damage analysis or both? What is the rite approach? 

2) In each of these cases, do I need to have a plastic yield function and damage surface ??  

The international conference is focused on the following topics:
