ANSYS CODE FOR FATIGUE CRACK PROPAGATION

Submitted by Amit S. Kulkarni. on Fri, 09/17/2010 - 18:11

Hi all,

Currently, I am using ANSYS 12.1 for the fatigue crack propagation simulation for the edge crack & center crack plates. It is a mixed mode crack propagation.

Can anybody please tell me or guide me how to write the code in the ANSYS using APDL for automatic remeshing around the cracktip when crack propagates to the new position?

Thanks in advance. :)

Concrete Smeared Cracking model in Abaqus

Submitted by mahmood seraji on Thu, 09/16/2010 - 07:05

research

I order to model the cement board material, i am going to use "Concrete Smeared Cracking" model available in Abaqus. I think I have to adjust some variables affecting the properties of the concrete to get the numerical load-deformation response close to that of the cement board.

I will be thankful if anyone help me.

Abaqus-Friction Element

Dear Friends,

I would like to know if there are any element in abaqus which may be used at the contact interface to account the frictionalal behaviour. I would appreciate if you show light on this.

Electromechanical concentration

Distribution of electromechanical field near electrode tips is closely related to the reliability of ferroelectric multilayer actuators. In this paper, the deformation and stress concentrations around the electrode tip in two multilayer actuator designs, partially and fully cofired, are investigated by means of experimental measurement and numerical simulations. The digital speckle correlation method (DSCM) is used to measure the full displacement field near the electrode tip with the high spatial resolution.
