Open Postdoctoral Position in Computational Science and Engineering

Submitted by Gail Small on Thu, 04/09/2015 - 13:35

The University of Notre Dame, Center for Shock Wave-processing of Advanced Reactive Materials (C-SWARM), is seeking a highly qualified candidate for a Postdoctoral Research Associate position in the area of computational mechanics/physics. C-SWARM is a newly established center of the emerging field of predictive science. The main mission of C-SWARM is to predict shock conditions under which new materials can be synthesized using predictive computational models that are verified and validated with quantified uncertainty on future high-performance Exascale computer platforms.

# Finite Element modeling

The current development of the isogeometric approach in various fields of mechanics is explained by the high-accuracy results which can be achieved at a reduced computational cost by codes based on non-uniform rational B-splines (NURBS). In the case of strongly curved beams the simple diagonal de Saint-Venant’s constitutive model can lead to significant errors as it has been reported in the classic literature. Other models such as Winkler’s have been proposed and seem more suitable for these kinds of structures.

Residual Stresses and Poisson’s Effect Drive Shape Formation and Transition of Helical Structures

Submitted by zichen on Wed, 04/08/2015 - 21:12

Strained multilayer structures are extensively investigated because of their applications in microelectromechanical/nano-elecromechanical systems. Here we employ a finite element method (FEM) to study the bending and twisting of multilayer structures subjected to misfit strains or residual stresses. This method is first validated by comparing the simulation results with analytic predictions for the bending radius of a bilayer strip with given misfit strains.

What is Extreme Mechanics?

Submitted by Zhigang Suo on Mon, 04/06/2015 - 11:56

EML

This question was raised repeatedly when the journal Extreme Mechanics Letters was getting ready to launch. The editorial board did put together the aim and scope. But the journal has its own life. Once launched, it has been shaped by the community.

getting the deformation gradient from abaqus

Submitted by kishan_Govind on Sat, 04/04/2015 - 11:16

Hello everyone.

I am trying to do something with the deformation gradient in UMAT. I used F=DFGRD0 as the gradient. but i found that it always comes to be a identity tensor not only for the case of a 3d isotropic elastic material but also for the ramberg osgood model. it was very surprising for me so i also tried to print DFGRD1 it was also identity tensor.

I have used a C3D8 single element and was doing the uniaxial test. Please help me out with this.
