We have a new position for posdoc in Qatar University. The main topic is using natural fibers in composite materials for particular structural applications. The job requires a previous experience in natural fiber composites. In addition, experimental and numeriacl tools are desirable. The salary is high (better than any other place). In addition, there are more benifits regarding schools of your children and the plane tickits. For more information, please contact me sepaey [at] hotmail.com. 

Hi all,

I am working on Crack growth analysis of Turbocharger wheel and shaft assembly. I have simulated it as an axisymmetric problem with fine mesh around the cracktip(in Ansys). Element used is Plane182.

I have to compare the K1 and K2 values obtained from both the Displacement Extrapolation Method and J-Interal method. 

I got the K1 an K2 values at the cracktip location by defining path using displacement extrapolation method.

But, I was not able to get the Stress intensity factor values (K1 nad K2) using J-Integral Method.

I've got problems using SPH (smoothed particle hydrodynamic), Is SPH
 analysis in ABAQUS coupled with heat transfer analysis??? I'm trying to
simulate Friction Stir Welding (FSW) with SPH Method, I need to predict
temperature  history during welding! Is there any software to do
this??? THANKS TO ALL

 I want to model lamb wave propagation in plate which is connected to sensors in ansys..Since i am completely new to it i am unable to solve multiphysics problem.So can any one plz guide me..

Hi 

i want to analysis a model in anasys workbench with modal analysis.but i Encountered to problem.Bad mesh generation (as you see in the below figure) happened that i don know how to solve it,could anyone help me ?

Regards,Ali 

Please I am currently having problem developing a UMAT for transformation-induced swelling material behavior.

I need help.

ABBA 

Hello everyone. I am new to Abaqus and was wondering how to create a model of a heat sink mounted on a heated silicon dioxide substrate. The substrate is on the left side and is a rectangle with a height of 40 mm and width of 5 mm. The heat sink is connected to the right of that with a parrellelogram shape, left side height of 40 mm (adjacent to the substrate), and right side parallel with a height of 5 mm. If anyone can help it is greatly appreciated. When I try modeling it, during section assignments it will not allow me to assign any sections. I have attached a picture of the model.
