Fatigue Crack Propagation Analysis by means of ANSYS

Submitted by Sanam Saebi on

HI Every Body

 I am postgraduate student of NavalArchitecture, My thesis is Fatigue Crack Propagation in ship Industry, I want to use Ansys Software for this purpose, at first I generated a plate with a central Crack and did fine mesh around crack and saw the results, for next step I should propagate the crack, my questions are as below:

1. How we can predict the Crack path?

2. how should I growth the crack? shall I clear mesh and extend the crack or.....???? I don't know?

3. How Can I use from Interface Elements?

If common block can be used in UMAT for parallel computing

Submitted by Wang Guofeng on

Hello everyone

I wrote some codes with umat recently .  They can work well with single CPU. However, the results become very bad for several CPUs. 

I define a matrix with COMMON BLOCK and it seems that COMMON BLOCK can not be used for parallel computing. Are there any ways to resolve this problem?

I am not familiar with fortran.Someone told me that the matrix should be defined by MODULE. I don't know about this.

Please give some helps to me

 

regards,

Analaytical Model

Submitted by psubbu2000 on

Hi all,

      If an analytical model predicts accurately all stresses, including transverse normal stress across thickness, using constitutive law for the analysis of laminated composite structures, what is the use of this model and where can  I apply this model in composite structures and fracture mechanics?. Further this model is amenable to linear/nonlinear finite elements with less degrees of freedom per node (C0 and C1 finite elements are possible).

 

Bye
