Hi Every body

I am Dhaneshwar Mishra, a PhD student working in the area of fracture mechanics, basically fracture failure of interfaces of bimaterial, composite layers etc. I am regular reader of IMechanica and got lots of insights by reading different postings on it. I am trying to model the interface in ANSYS 10.0 with their Interface element INTER204. While searching this element in Ansys element library, i could not find it. Will some body guide me to model interface of composite layers using the concept of cohesive zone modelling?

Thank you

Recent events about the financial crisis and generally spread turmoils on Economics and Financial Environments  lead me to these conclusions.

Critical Speed:  informations, a key issue on finance, reached a critical speed. Maybe this is the "first" critical speed of the system. Speed of informations has reached the same order of magnitude of people's judgement (executives and investors more than others) so there's a sort of over-reaction about actual events.

how can we analyse fatigue crack by using ansys and find the optimum hole for arresting cracks.

thanks to all.

 Recently, enlightened by the definition of inverse pole figure in Materials Science, I proposed an inverse-pole-figure (IPF) method for analysis of domain switching in polycrystalline ferroelectrics/ferroelastics.
