The nonlinear dynamics laboratory at the University of Rhode Island has an open position for a PhD student supported through research assistantship (including tuition remittance) starting Summer or Fall 2016. This position is supported by NSF grant. This research has a multidisciplinary nature incorporating material science, dynamical systems modeling, fatigue testing, and nonlinear time series analysis.

ABAQUS, partitioning an edge

partitioning edge

Abaqus python script

Hello Everyone,

Does anyone knows how it is possible to partition an edge in one step with multiple points (like multiple datum points or multiple parameter values)? I know how to partition one edge one by one. The problem of doing it one by one is the amount of time that it takes to do that. For example if I want to put 50 points on one edge I have to pick that edge 50 times and partition it, which takes a lot of time.

I am doing the whole process by scripting with Python so I would be glad if the solutions are in scripting format (I am using ABAQUS 2016).

Thanks,

Effect of extension twins on texture evolution at elevated temperature deformation accompanied by dynamic recrystallization

Submitted by ystarase on Thu, 04/14/2016 - 11:47

High temperature deformation processing of magnesium and its alloys is often
accompanied by dynamic recrystallization (DRX). Deformation twinning is one of the main
deformation mechanisms in HCP metals, but very few works are available in literature
(experimental or modelling) which investigate the effect of the deformation twinning on
dynamic recrystallization. The current study provides insights regarding the deformation
mechanisms of magnesium alloy during compression test at elevated temperatures

Reconstruction of the 3D representative volume element from the generalized two-point correlation function

Submitted by ystarase on Thu, 04/14/2016 - 11:46

This paper presents the first application of three-dimensional (3D) cross-correlation
microstructure reconstruction implemented for a representative volume element (RVE) to
facilitate the microstructure engineering of materials. This has been accomplished by
developing a new methodology for reconstructing 3D microstructure using experimental two-
dimensional electron backscatter diffraction data.

how can i model a BRB Brace in abaqus

hi every body

I model a brb(Buckling restrained brace) in Abaqus but my question is How to put concrete in a brb or How do I define the concrete inside the brb that work together? i use tie constraint But there isn't any stress for concrete!
i use static,General for analysis! is it correct?

The STFC Hartree Centre (in Warrington, UK - located between Manchester & Liverpool) is running 4 high performance computing summer schools from June to July 2016. They are primarily aimed at PhD students and postdoctoral researchers, but are also open to academics and industry at no extra cost. The tuition fees are subsidised by STFC and each week only costs £150. There is a 1 week school on each of the following topics:

Post-doctoral position in Computational Materials Mechanics at NUS, Singapore

polymers

We have an opening for a post-doctoral fellow position in multiscale computational mechanics of polymers. The project focuses on modeling and simulation of the thermo-mechanical behavior of polymers with covalent adaptable networks (CANs), e.g. vitrimers. The objective is to formulate a hierarchical modeling and simulation approach, which closely mimics key steps in the recycling and reshaping processes of CAN polymers by embedding the physics at two length-scales – (i) discrete-continuum (meso-scale) and (ii) homogenized continuum (macro-scale).
