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 Thu, 10/23/2008 - 08:15

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,

Wang

Analaytical Model

Submitted by psubbu2000 on Wed, 10/22/2008 - 16:03

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).

How to get information of boundary conditions when writing UEL in ABAQUS

Submitted by An Danh Nguyen on Wed, 10/22/2008 - 15:35

Hi all,

I need to get information of boundary conditions for prescribed nodes when writing UEL in ABAQUS. Could anyone tell me how to do that?

Thank you very much in advance.

Cheers

Danh.

Mechanics of Materials by F.P. Beer, E.R. Russell Johnston Jr. and J.T. DeWolf

Submitted by Pawel Zimoch on Wed, 10/22/2008 - 14:51

Mechanics of Materials is the book I used for my undergraduate course in strength of materials and it helped me understand the basics, and hence my selection.

The outline is as follows:

Ch. 1: Introduction - concepts of stress

Ch. 2: Stress and strain - axial loading

Ch. 3: Torsion

Ch. 4: Pure bending

Ch. 5: Analysis and design of beams for bending

Ch. 6: Shearing stresses in beams and thin-walled members

Ch. 7: Transformations of stress and strain
