Nine papers about fatigue modelling of short fiber composite

Recently, we have published a series of nine papers about modelling fatigue and damage in short fiber composites.  Together, they provide a complete description of modelling of such materials including wavy fiber composites; starting from appropriate homogenization method to component level fatigue simulation. Discussion and feedback on the papers is welcome.

Graphene is softer to bend when stretched and bent and harder to stretch when bent and moderately stretched

 

In the attached paper, we have shown that concomitant bending and stretching, whatever their value, concur to make bending stiffness decrease; moreover, concomitant bending and stretching make the stretching stiffness (or the Young modulus) increase until the applied forces reach a threshold value, then they make it decrease. Said differently, graphene is softer to bend when stretched and bent and harder to stretch when bent and moderately stretched.

 

Writing UHYPER for photo-thermal sensitive hydrogels described in the thermodynamic framework?

 Hello

I`d like to write a UHYPER for photo-thermal sensitive hydrogels described in the thermodynamic framework. But the photo-chemical term in the energy equation is 7order greater than the others. The other terms are related to stretch and mixing energy they exist also in the temperature sensitive hydrogels energy equations and their UHYPER is valid.  I have checked all the coefficients, their orders are all correct.

Underwater Soil Mechanics Problem

I am an undergraduate student conducting a research project involving the design of a tool to aid astronauts to perform experiments on lunar surfaces and would like to request some direction about which analytical tools would be best suited for this application (i.e. FEA or DEM software/techniques). The specific scenario of interest is to design a tool that can act as an anchor in a sand-like medium (regolith) on the surface of the moon.

Post-buckling analysis of plates?

Hi

I want to write a finite element code capable of modeling the pos-buckling behavior of plates. I have already written a FEM code for eigenvalue buckling analysis of plates.

I don't have any idea how to start.

I would be very grateful if someone could help me

thanks

Does a single crystal have a net rotation after you load and then unload it ?

To detail out,

My understanding of multiplicative decomposition of deformation gradient F =FeFp  (see the attached figure) is

Fp indicates the shape change without inducing any stress
Fe leads to elastic stretching and rotation

 

Say, If I load a single crystal and unload it, we will have a residual plastic strain present. As, we removed the load, the effect of Fe would have been gone. So all the elastic effects vanish.

which kind of homogenization can we use?

hello every one.

If we consider dislocation effect( GNDs) that they have proportional relation with strain gradient, does it effect on way of homogenization or not? i mean at this situation can we use any methods of homogenization ? I'm looking into size effects at micro scale on macroscopic properties.i want to be sure if self consistent method is usable to as a method or not?

Postdoctoral Position in Applied Mechanics

<p>A post-doctoral position in the general area of continuum simulations of high-strain rate impact phenomena is available in the Mechanical Engineering Department at Northeastern University. The specific goal of the project is to investigate the mechanics of cohesion following high velocity impacts. Knowledge of finite element theory, contact mechanics, plasticity and cohesive zone using customized codes and Abaqus are required. Experience with writing own finite element codes, Abaqus user subroutines and Python code will be helpful for the position.

Assistant or untenured Associate Professor - Stanford University

The Department of Electrical Engineering at Stanford University (http://ee.stanford.edu/) invites applications for a tenure-track faculty appointment at the junior level (Assistant or untenured Associate Professor) in the broadly defined field of electrical and computer engineering. The department is especially interested in candidates in robotics and autonomous systems, hardware systems, and embedded systems. Priority, however, will be given to the overall originality and promise of the candidate’s work over any specific area of specialization.

Postdoctoral Fellowship in Computational Neuroscience (but embedded in a mechanics group)

I realize this is a bit off topic from traditional iMechania job posts, however our group is primarily a computational biomechanics group. We conduct much research in the area of brain biomechanics and more recently are working to move into multiphysics and multiscale areas of brain science. This project, funded by the NIH Brain Initiative, focuses on growth and bioelectric simulations of neuronal cell networks.
