Modelling crack in Ansys with interface elements

Modeling Crack with interface elements in ANSYS

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.

Modeling of large strain deformation in Abaqus

Hi everybody,

I'm trying to model large strain deformations in Abaqus by writing a user defined material code in order to implement the governing constitutive equations of the material. As far as I know, Cauchy stress tensor should be used in the model to presume non-linear finite elements, but I don't know how one can implement Cauchy stress tensor in a UMAT used by Abaqus.

Thanks,

Hadi

An inverse-pole-figure method for analysis of polycrystalline ferroelectrics/ferroelastics

 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.

Modeling masonry in ABAQUS

Submitted by dhruba on

I am quite new to ABAQUS and trying to model structural masonry.I am facing difficulties in defining material property and analysis procedure.I was wondering if anybody has worked on this particular area and provide me with some useful resources.

 Any Help in this regard will be highly appreciated

Thanks and Regards,

Dhruba
