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.

USNCCM12 MS4.9: Concurrent Multi-Length Scale Modeling: from Finite Elements to Atoms and Electrons (call for abstract)

We cordially invite you to participate in the 12th U.S. National Congress on Computational Mechanics (US-NCCM12) and give a talk in our minisymposium (MS4.9) entitled "Multiscale Concurrent Multi-Length Scale Modeling: from Finite Element to Atoms and Electrons". The Congress will be held in Raleigh, NC, USA, from July 22 to July 25, 2013.

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!
