Composites

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

Micromechanical modeling

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

Ghouse

strain softening behaviour

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

Setareh

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.
