Cohesive Zone Model for FGM

joabson — Thu, 19 Jun 2008 10:04:07 -0400

Hi,

i am working on fracture in FGM shell element applying cohesive zone model. So, i am including the rotation effect in the Xu and Needleman´s potential and using 3D interface line element. I´d like to know if there are someone doing something similar.

Thanks for all

hi all

i would like to have some assistance from all regarding crack propagation in annular disk at tang location using ABAQUS

Manufacturing of FGM

Sandip Haldar — Sat, 04 Aug 2007 02:52:15 -0400

Hi,

In the theoritical/computational analysis, one or more propertis are assumed to vary according to some function. I was interested to know (mainly from manufacturing/experimental groups), what are the properties that may be varied or if they may be varied according to any mathematical function or not. It will be helpful to get some works regarding this.

shells

BoJing Zhu — Tue, 31 Jul 2007 09:48:28 -0400

hi,

our group is studying 3D cracks problem in fully coupled electromagnetothermoelastic multiphase composites about 8 years.

perhaps i think we can solve shell crack problem byhypersingular integral equation method

if you interested this method you can find related papers on web: Noda, N.A; Taiyan Qin; Renji Tang; Mengcheng Chen; Chaojin Yue; Chunhui Xu; Pan ernian et al

Factories which product FGM

Adel Samiei — Sun, 29 Jul 2007 12:40:29 -0400

Hi all,

I want to know which factories product FGM.

Thanks.

Is it possible to product FGM plates?

Adel Samiei — Fri, 27 Jul 2007 14:46:51 -0400

I am Adel Samiei.I am working on the vibration and natural frequency of functionally graded materials.I want to know is it possible to product FGM plates in a Factory?

Thanx

Optimization in FGM

hi all

i want to get some literature for finite element analysis of FGM shell. currently i am working on the multiobjective optimization of fgm shells.

with regards

vikulp sharma

Thanks for the papers

Dear Mishnaevsky,

Thanks for the papers. I will examine power law fgm first, and then

sigmoid and exponential fgm.

Micromechanical modelling of Functionally Graded Composites

Leon Mishnaevsky — Wed, 04 Apr 2007 04:32:22 -0400

Ulukoy,

we carried out some numerical simulations of deformation and damage behavior of Functionally graded Composites. In so doing, we considered first a particle reinforced composites with graded particle distribution and non-percolating microstructures, and then graded interpenetrating phase composites. You can download papers from http://www.risoe.dk/afm/personal/lemi/, in particular, http://www.risoe.dk/afm/personal/lemi/papers/voxel-paper.pdf and http://www.risoe.dk/afm/personal/lemi/papers/paper_fgm.pdf.

numerical analysis of fgm

ulukoy — Wed, 04 Apr 2007 04:10:39 -0400

Hi,

i'm interested in numerical analysis of fgm. but i need apdl codes for describe material properties of fgm.

Can you help me?

Thanks.

Suggest me basic book on FEM

NEERAJ BHARDWAJ — Mon, 02 Apr 2007 10:44:44 -0400

Dear Prof.Sandy

Good Morning

I am NEERAJ BHARDWAJ. My group is working on VIBRATION OF PLATES AND SHELLS. We are very curious to study on VIBRATION as well as Thermal effect on FUNCTIONALLY GRADED PLATES. But, we have no idea about it. Please suggest me the some basic books on functionally graded materials which would help for beginners.

With best of my regards

About FGM plates etc

Ji Wang — Sat, 31 Mar 2007 23:30:46 -0400

I am glad to see there are overwhelm interests in the FGM and applications. We have been working on FGM for about two years with sponsored projects. Major research work are being done by Prof Zheng Zhong, Tongji University, Prof Weiqiu Chen, Zhejiang University, with a number of collaborators in other schools.

The basic approach has been usual: particular pattern of FGM which can give you analytical solutions first, then extended to other schemes.

For myself, I am intersted in FGM in acoustic wave devices, which may lead to new device structures. We have some results and publications, and more results are in the pipeline.

What we have found is also usual: the differential equations fromthe complicated material property change can be solved by Forbenius Method. Lately, we are tryign to use the HAM (http://numericaltank.sjtu.edu.cn/) for the equations to be solved.

For books, one by GR Liu, CRC Press, maybe closer to the analysis and FEM part.

It is always great to meet colleagues on the same subject.

Dear Dr. Bharadwaj.

Dear Dr. Bharadwaj,

The following book Fundamentals of functionally graded materialsS Suresh and A Mortensen

is a very good book to start.

Functionally Graded Materials

Dhirendra Kubair — Fri, 22 Dec 2006 12:59:03 -0500

Dear Fellow Mechanicians,

My group is looking into some aspects of fracture in "functionally graded materials". I was curious to know if there are groups (on imechanica) interested or actively pursuing research on functionally graded materials or nanocomposites.
