Hi, I am sutdding the dynamics of a plate supported in all sides made
with composite with de following characterisitcs: (1.) composite
configuration [ (0)_2 / (90)_2 / +45 / -45 ]_s (2.) hickness of the
layers [ 2*h/12 / 2*h/12 / h/12 / h/12 ]_s where h=0.6mm (3.)
dimensions a=b=0.6 by using ANSYS element SHELL 99.
Hello,
I am currently reading a book about "Material Inhomogeneities in Elasticity" written by Gérard Maugin.
He brings up the covariancy and contravariancy of some well-known stress tensors and in particular that of the Cauchy stress tensor. I was not very familiar with the concept of covariance, so i read up on this very specific tensorial notion.
I have been able to demonstrate easily that the deformation gradient F is a mixed tensor (covariant and contravariant).
Is it possible to carryout the Fatigue Analysis using LS Dyna.
If it is not possible then what will be the best software to carry out the analysis.
Hi guys,
Since I graduated in Germany and I'm looking for a
postdoc position in the States I come across these requested 'letters
of interest' and I really don't quite know how I'm supposed to be exactly composing those.
I'd really appreciate some help. Thanx a LOT!!!
PS I already tried google! ;)
I was surprised and delighted to see your name as it is the same name as my brother and three (3) of my 1st cousins here in the USA. regards, Lenore @ diamondsadpearls [at] aol.com (diamondsadpearls[at]aol[dot]com)
Has anyone created a UMAT user subroutine for concrete, capable of cyclic loading. I am interested in modeling a composite steel frame with concrete slab, and the "Damaged Plasticity" model in ABAQUS has convergence issues with the cyclic analyses. If it is possible to get a copy of your UMAT, I am very interested.
Thanks

Hi everybody,
I'm trying to model large strain deformations in Abaqus by writing a user defined material code in order to implement the governing constitutive equations of the material. As far as I know, Cauchy stress tensor should be used in the model to presume non-linear finite elements, but I don't know how one can implement Cauchy stress tensor in a UMAT used by Abaqus.
Thanks,
Hadi
Has anyone here tried to impose essential bcs on material points in MPM? I know there are a couple of methods available for other meshless methods such as EFG and RKPM, I was wondering if anyone has tried extending them for MPM.
Thanks,

Hi guys..i am an abaqus CAE user and i am creating a model of an annular disc with a clamped at the middle hole. I have to compare the result of the stationary one with the rotating one. But I did not know the command for a rotating disc, as I have tried, I used the rotational body force. The problem is the result is the same as the stationary one which is wrong! i am a beginner at this, so could somebody help me out here, please?
