Key Qualifications

MIT Postdoctoral Position in Finite Element Analysis for DNA nanotechnology

Submitted by markbathe on

The Laboratory for Computational Biology and Biophysics at MIT (http://lcbb.mit.edu/) is seeking a highly motivated recent PhD graduate with expertise in nonlinear finite element analysis, ideally in the area of beam theory, with a keen interest in applying this knowledge to molecular modeling of DNA-based nanostructures. The candidate must have excellent written and verbal communication skills, PhD-level training in finite element analysis, and a strong record of publishing archival journal articles.

Boundary conditions for strain based loading

Submitted by rpd25 on
Hi,

I would like to perform a loading on a 2D specimen using a commercial software to obtain a stress-strain curve for  shape memory alloy (using the Ginzburg-Laundau model). To obtain the stress-strain curve following methods can be applied (refer to the figure for the nomenclature of boundaries)

(a) Displacement based loading: Constraint (Dirichlet boundary condition) the boundary 1 (in x and y direction) and load the boundary 4 in the x direction.

Traction Prediction of a Smooth Rigid Wheel in Soil using Coupled Eulerian-Lagrangian Analysis - 2012

Submitted by SIMULIA on

The approach to modeling soil is validated by comparing predicted traction of a trolling rigid wheel to measured traction test date available in the literature. Comparison of the measured and predicted traction force shows that this approach is reasonable for predictin traction in soil.

Integrated Tool for Strain Extraction in Virtual Testing - 2012

Submitted by SIMULIA on

This paper presents an automated approach to extract strains of aircraft structural models from widely used CAD and FE environments. The developed approach has been implemented as an integrated tool in widely used CATIA V5 and Abaqus environment. The integrated tool is a quick inexpensive and effecive technique for predicting structural strains.

Modeling the COnstitutive Response of Metals Under Complex Loading - 2012

Submitted by SIMULIA on

In this paper, the different "built in" material models based on the isotropic, kinematic and combined istropic-kinematic hardening theories available in Abaqus/Standard are evaluated for carbon steels. The results presented in this study are expected to provide important insight to practicing engineers dealing with inelastic material characteristics.

Structural Topology Optimization of Multilink Suspension System Using ATOM - 2012

Submitted by SIMULIA on

This study demonstrates a simulation of an integrated multilink suspension system model in

Abaqus. The model is assessed in Abaqus to determine the suspension strength and fatigue life of each individual link. This topological design optimization is executed for this multilink suspension model using ATOM to determine the critical load path, alternative concept designs, and locations for mass reduction in order to meet the performance requirements.

Thrust Collar Bearing Design Optimization using Isight - 2012

Submitted by SIMULIA on

This paper describes the parameter-based geometrical optimization of a thrust collar bearing. The thrust bearing, for example, has to carry the whole axial force of the rotor with only minimal deformation of the collar surface over the turbocharger’s complete operating range.

Pipeline Dynamics with Flowing Contents in Abaqus/Standard - 2012

Submitted by SIMULIA on

This paper discusses a method to address this challenge by the creation of a moving

tie constraint via the MPC user routine. This approach allows the change in weight; change in inertia and effects of fluid momentum to be correctly and conveniently captured using dynamic modelling.
