Layered Material.

I want to get some information about layered material and its property and nutural plane in bi metal plate while bending.

Re: Layered Material
This is a classical problem and there are many papers on the subject. Here is one that might get you started:
Z. Suo, E.Y. Ma, H. Gleskova and S. Wagner, Mechanics of rollable and foldable film-on-foil electronics. Appl. Phys. Lett. 74, 1177 (1999).
You could found it in the book.
You could found it from the book "Mechanics of Materials"
Or from the appendix III in "Suo, Z., Hutchinson, J.W., 1990. Interface crack between two elastic layers. Int. J. Fracture 43,1-18."
Ying Li Department of Engineering Mechanics Tsinghua University Beijing, 100084, P. R. CHINA
neutral plane
I would like to point out that the concept of neutral plane should be used with caution for two-dimensional bending of multilayered plates. The references given above considered only one-dimensional bending, like the classical beam theory, in which case the neutral plane can be defined with no ambiguity. For two-dimensional bending (with two non-zero principal curvatures) of multilayered plates, however, an ideal neutral plane (with zero in-plane strain in all directions) does not exist, unless all the layers are isotropic, linear elastic with identical Poisson's ratios.

Pure Bending.(isentropic Material)
How to find the location of nutural plane from the Bimetal layered plate subjected to Pure bending??.And on what basis its changing in layered materia(isentropic material e.g-Mg?Thx ...............
I am doing my final year project "FEA (ABAQUS)Layered plate analysis under pure bending"and its similarity and problem with practical and simulation results.
isentropic or isotropic?
Hardik,
What do you mean by "isentropic material"? If you mean "isotropic", I can send you a formula to calculate the location of nuetral plane for bilayered plates, again under the condition of homogeneous Poisson's ratio, if you give me your email address.

isotropic....
Sorry,sir,
(Rui Huang)
Its fully my mistake, its actually isotropic Material.and Thx for your co-operation.My email - hkpa@deakin.edu.au

Please see the file attached to your original post.

HI SIR, I have one
HI SIR,
I have one confusion about anostropic material ,How can we find nutural plane location in bi-metal plate.we can consider same as isotropic material criteria for this?.And is it possible to simulate isotropic material in ABAQUS?
