Composites

Two postdocs at U. Pittsburgh

Two post-doctoral positions are available in the lab of Sachin Velankar in the Dept. of Chemical Engineering at the University of Pittsburgh to conduct experimental research on the biomechanics of surface texturing in cephalopods (octopus or cuttlefish), and to devise reversibly-morphing surfaces.  These animals are famous for their camouflage abilities.  Like many other animals, cephalopods can change their color, but in addition, they can also change the texture of their skin by expressing protuberances or wrinkles.

Unit cell modeling using Abaqus submodeling

Hi,

I was going though papers related to micromechanical modeling of composites using unit cell approach. Usually in this procedure, a unit cell is isolated from the material and to ensure the compatabilty of the unit cell boundary, periodic boundary conditions are applied.

To ensure the compatabilty of the boundary and to apply loads, can we use submodeling techniques available in ABAQUS.

Thank you

Regards

mesh dependence of continuum damage mechanics approach

Hello Everyone,

I am a beginner in FEA of composites under impact in commercial explicit code Pam Crash.I want to know why the behaviour of composite plies with CDM approach show mesh dependency?Or a more general question for me is that what makes the FE simulation of a material with strain softening behavior mesh dependence(If this conclusion is right)? Does it make any difference with regard to mesh dependency if one uses implicit codes??

Thanks

Reliability and engineering mechanics

The word "failure" can mean different things to different people.  Over the past couple of years, my interactions with various groups from industry has shown me that for some people failure means catastropic fracture/buckling while for others it can mean highly localized plastic yielding.  Even for relatively simple sandwich composite structures, there is no clearly agreed upon definition of the word.

ECCOMAS Thematic Conference on the Mechanical Response of Composites - Abstract Deadline 17 December

The conference provides an efficient platform for experts on composites analysis. We are very pleased that the 2011 Public Forum of the EU Project MAAXIMUS (More Affordable Aircraft through eXtended, Integrated and Mature nUmerical Sizing, www.maaximus.eu) will be part of our ECCOMAS Thematic Conference.

Lecture Notes on Composites

In addition to the notes on stability that I've already posted, I have a set on Composites, which also originated from a lecture course that I gave in Ecole Polytechnique, around 2002. In the hope that they may be of interest at least to someone, here they are! Please do remember that they are just notes and may not be error-free.

Transverse moduli for composite

I'm currently working on modeling 3 phases composites material. However, I'm having hard time on finding the transverse modulus as it's different from analytical results. I've been using Mori-Tanaka approach to determine the stiffness moduli. Does anyone know how to obtain a correct values for the transverse moduli?
