Two Postdoc + two PhD Openings in Topology Optimization, Cardiff University, UK

Applications are sought for four Post-Doctoral Research Associates and two PhDs to join a very active research group at Cardiff University, UK (School of Engineering).  Based in Cardiff, there will be frequent interactions with the University of California, San Diego as well as major aerospace companies in the UK. The research will formulate and develop numerical methods for mulitiscale and multiphysics design optimisation using level set topology optimization.

A multi-scale modeling framework for instabilities of film/substrate systems

Spatial pattern formation in stiff thin films on soft substrates is investigated from a multi-scale point of view based on a technique of slowly varying Fourier coefficients. A general macroscopic modeling framework is developed and then a simplified macroscopic model is derived. The model incorporates Asymptotic Numerical Method (ANM) as a robust path-following technique to trace the post-buckling evolution path and to predict secondary bifurcations.

PhD position in the area of atomistic-based modelling of polymer composite degradation

Applications are invited for one PhD position (4 years) in the area of atomistic-based modelling of polymer composite degradation at Delft University of Technology in the Netherlands.

The successful applicant will work with Dr. Angelo Simone (Computational Mechanics of Materials Group) and Prof. Barend Thijsse (Virtual Materials and Mechanics Group) on a project funded by the Technology Foundation STW through the High Tech Materials program. The position is to commence in spring/summer 2015 or as soon as possible thereafter.

Averaging and Homogenization in multiscale methods

I found this reference very helpful in building a solid base for learning the foundamentals of Homogenization methods and up to now, is the only reference that addresses the difference between Homogenization and Averaging methods.

I will put more references in this entry and will be happy if you share your links with me.

Sutured tendon repair; a multi-scale finite element model.

We've recently published an open access journal paper that looks at the mechanics of sutures used to repair severed tendons. A homogenization strategy is used to derive effective elastic properties for tendon fibrils and intracellular matrix. We have found that regions of high stress correlate with the regions of cell death (necrosis) that are sometimes observed in patients.

If this is of interest, please feel free to view the paper here.

A review on multiscale methods for material modeling

Dear all,

Please find enclosed our paper which is published on Journal of Multiscale Modelling
Vol. 3, No. 4 (2011) 1–
42 which gives an overview of state of the art multiscale techniques for material modeling. 

The paper discusses the following topics: homogenization, Representative volume element, computational homogenization (Fe2 methods) for both both bulk materials and strong discontinuities. 

I hope the paper is useful for beginners to the field.

All the bests, 

Abaqus multiscale bridge with UMAT

Choose a channel featured in the header of iMechanica: 

Hello,

I'm trying create a bridge between scales using Abaqus, UMAT subroutine.

On macro scale I call UMAT, which calls other abaqus inp. with this example code

call SYSTEM('abaqus cae script=C:\Temp\mixUMAT\simpleModel.py -- A 2 5.3')

And my "simpleModel" receives all arguments properly.

However, I need some values which are calculcated on "simpleModel", to UMAT continues the executation.

Anyone knows  how can I do it?

 

Thank you!
