3D crack modeling using CTMOPT macro in ANSYS

Hello Everybody..

I am MS student in University of cincinnati, Oh, USA. I am working on
fractures in thin film and for  that i need to model 3D cracks. Problem
is i cant just use extrude comand becuase, crack is not throughout tht
length of the film ( So i cant use th eapproch mentioned above). there
is CTMOPT macro in ansys which allows to desgin meshing at the crack
tip. I am struggling with the ewxplanation given there. If anybody has
detail information in how to implelment this macro, please let me
know. 

Thanknig you,

Hi,

 I want to know what are some useful softwares in which I can simulate multilayer coatings in terms of thermal (CTE mismatch) stresses, and stresses due to contact type loading. I am looking for softwares that are easy to use by a person like me who has an experimental background, does not have exposure to using Abaqus, but can use softwares like Matlab.

 Thank you in advance for your suggestions.

Regards,

Sudhir

A postdoctoral associate position at MIT is available immediately, focused on elucidating the fundamental material science concepts that control the formation, behavior and in particular mechanical failure and fracture of fibrous amyloid protein materials. Amyloids form pathogens in diseases (Alzheimer’s, Parkinson’s), play a role in defining the properties of spider silk, and are found in many natural adhesives. These beta-sheet rich protein structures constitute an intriguing class of protein materials that self-assemble at room temperature to form characteristic hierarchical nanostructures and fibers, which combine exceptional strength and sturdiness, elasticity with bioactivity and the ability to self-heal.
