failure

Hi everyone. I'm new to this forum and quite new with FEA.

Currently i'm trying to find compressive strength or maximum failure stress on a modeled brick. Is't possible? What parameters or properties do i need in hand in order to proceed?

Regards,
KenLo

nonlinear finite element formulations

ask imechanica

Dear All,

I am a Masters Student in Material Science, I am supposed to do the Finite

Element modeling of PTFE material with few content of short carbon fibers. Could any of you please suggest the best,

1.Modeling method, its

2.Material parameters and

3.References of that best modeling method.

Would be really thankful and would be helpful for my studies as well.

Regards,

FEA

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.

Shell

Hello,

sorry for my bad english,

I want help for VUEL Abaqus subroutine, I don't no how to compute the time increment for stability for the shell structure.

Thank u.

principal directions for 4th order tensor

Submitted by whitman on Fri, 02/13/2009 - 16:12

Is it possible to find eigenvalues and principal directions for a 4th order tensor? How?

For a zero order tensor? for a first order tensor? for a third order tensor.........

many thanks

Modelling Ice deformation and fracture in Abaqus

Submitted by Daniel Prawica on Fri, 02/13/2009 - 01:52

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.
