2D approximation of heterogeneous 3D media

Submitted by phunguyen on

Dear All,



Could somebody indicate me some literature about the topic "2D
approximation of heterogeneous 3D media"?



In particular I am interested to address following issues:



1) Under which conditions averaging thermal conductivity and young
modulus (or more general, mechanical behaviour) on multiple 2D crossections of an heterogeneous "random"
material can be a good approximation for the behaviour of the real 3D
microstructure

Producing Stress Analysis from Strain data

Submitted by G Rezk on
Choose a channel featured in the header of iMechanica

I am doing research on the stresses that are produced when a retainer (a thermoplastic sheet) is placed on the teeth. We've designed the project so that we take an initial scan of the sheet and a final "shifted" scan of the sheet. We'd like to compare, find the strain, and calculate the stress neccessary to produce this strain.

I was hoping to use FEA for this...is it possible? I have access to Abaqus and Ansys, and where can i find the commands that allow me to do this.

Modelling Ice deformation and fracture in Abaqus

Submitted by Daniel Prawica on

Hello Abaqus Users,

I am new to Abaqus: I am trying to model formation and propagation of fractures in glacial ice (note: ice deformation mainly by plastic flow). I was wondering if anyone has modeled ice as a material exhibiting a nonlinear behavior, or possibly have a user subroutine for ice that I could use. Thanks in advance for any help.

solver for a very hetereogeneous system of equations

Submitted by phunguyen on

Hello everybody,

I am solving a FE problem on a hetereogeneous medium consisting of rigid phase (Young modulus of about 100 000 N/mm2), a softer phase (Young modulus of 20 000 N/mm2) and pore (Young modulus of 1 N/mm2). The reason that I have to mesh the pore is that there are some elements of rigid phase hanging out in the pores. So, if I do not mesh the pore, then my FE matrix is singular. 

Abaqus SE problem

Submitted by Richard Kutcher on

Just attended a FEMA introduction course put on by my provincial engineering assoc.  We all received a copy of Abaqus Student Edition.

When I install the program on my Toshiba Windows Vista laptop the installation completes but when I start the program and try to draw a part instead of getting a blue grid I get a second white drawing sheet overlaying the first.I have tried numerous installs and have all the latest Vista upgrades.  My copy of the DVD is good because the program works on my desktop computer.
