Near-incompressible analysis

Submitted by Alejandro Orti… on

Hello all,

I am studying some simple finite elements for 2d near-incompressible analysis. Particularly, I am interested in the MINI element. It is basically a 3-node triangle element with nodal pressure and displacement degree of freedoms enriched by a bubble function. Could someone that has some experience with these elements point me out about advantages and drawbacks of using these type of elements?

Thanks,

Alejandro.

Self-consistent Modeling of plastic and viscoplastic polycrystalline materials

Submitted by T.ZENG on

I am a freshman of researching the macro response of  metals with micromechanics scheme. Now,I have to build a  self-consistent modeling of plastic and viscoplastic for polycrystalline materials. However, it seems difficult for me as I have little knowledge of polycrystalline and its mechanics propertities.

If you know some systematic books or papers about my research area. please let me know. Your kindness will be great appreciated!!!

What yield criterion must I use?

Nowadays I am analyzing a study of a hip prosthesis including the bone. I am making the FEA/FEM analysis by Pro/Mechanica software. Metallics materials are titanium alloy (Ti-6Al-4V) and Chromium-cobalt-molybdenum alloy (CoCr29Mo). So they are ductile materials. I understand the main load is the flexural load on the hip.

Hi everyone. I'm new to this forum and quite new with FEA.

Currently i'm trying to find compressive strength or maximum failure stress on a modeled brick. Is't possible? What parameters or properties do i need in hand in order to proceed?

Regards,
KenLo

concrete damage plasticity model in abaqus

Submitted by chakradhara rao on

I am doing plain concrete beam subjected to low velocity impact model in abaqus. for model the concrete i have choosen concrete damaged plasticity. Is it the proper selection for model the concrete under dynamic loading. If it is correct, how to get the tensile behaviour of concrete (yiled stress, cracking starin) from uniaxial test data (yiled stress, inelastic strain). Please help me if any body is having the idea on this.

2D approximation of heterogeneous 3D media

Submitted by phunguyen on

Dear All,



Could somebody indicate me some literature about the topic "2D
approximation of heterogeneous 3D media"?



In particular I am interested to address following issues:



1) Under which conditions averaging thermal conductivity and young
modulus (or more general, mechanical behaviour) on multiple 2D crossections of an heterogeneous "random"
material can be a good approximation for the behaviour of the real 3D
microstructure
