Contact analysis in Abaqus
Dear Friends.
I am trying to model a moving truck on a bridge . Initially I want to try doing a static analysis. For this , I have modeled tyres as analytically rigid cylinders and, placing them on the solid slab element . After this i have applied a velocity boundary condition to the rigid cylinder , and also a load ( Pointing in the direction of gravity) to the reference point .
XFEM
The new feature of XFEM was added to the ABAQUS6.9-2. Does anybody
know how can I extract the current configuration of crack in terms of distance
values from nodes? I know that PHILSM provides information on this issue, but
it is only about crack plane. I want nodal distance from crack front
A funny error
Dear All,I have written a finite element code in C++. The results have generally high accuracy. But when I change the order of evaluating r and theta of the polar coordinates in terms of x and y in the sub-program of computing the shape functions, then the results are changed about 10^-9 of the initial results. The change is negligible but I wonder why this happens? I had initially supposed it may be related to some memory linkage in the program but since now I have not been successful to find any. Is there any one to have an idea about this funny error???

from NIT calicut , need help in Ansys modeling cracks in offshore tubular joints
hi everyone,
i am doing my masters in offshore structures, as part of my thesis work i am doing fatigue analysis of offshore tubular joints. So , i have modeled the typical joints( T joint, K joint and Y joint) in ansys, now i have to model the cracks to find stress intensity factors, then i ahve to estimate fatigue life.
Can anybody pls tell me how to model the crack in Ansys classic, if u have any tutorials or examples please send me.

Sigma Technology shares the success of aircraft buiders (IOSO news)
29 January 2010 New Russian Fifth-Generation Fighter made his first flight. This aircraft was designed by company Sukhoi with the new engines designed by NPO Saturn. We would like to express our proud and mention that both companies have used IOSO Optimization software as a regular part in their design and development technological cycle.
Career after the Ph.D.
Hi,
I'm an Engineer and a Ph.D. student in Applied Maths, working in the field of Nonlinear Finite Elements for Elasticity. I often think about my future career since, by now, I have a strong experience with coding FE in C++/Matlab/Mathematica, but no clue whatsoever about commercial black-box softwares for FEA. I'm worried about this, since most of the job vacancies from the industry (I'm not interested in pursuing the Academic career) seem to require only experience with a specific software and application, and not to directly code FE.
3D Modeling of Cracks
Hi every body, i want to simulate the cracks in 3D models.
Thank You
