composite plate analysis in ansys

Submitted by priyabratadas on Wed, 10/26/2011 - 07:37

can anybody tell me how to model composite plate in ansys?? And how to solve it? Specify me what type of element should be used.

Is it a bug? can't manage displacement amplitude when applying it via function

harmonic displacement

Hello,
everyone!

I’m trying
to simulate different types of acoustic waves in linear anisotropic crystal in
order to measure their propagation speed (phase speed), and compare it with
experimental data.

Empirical observations of temperature

I have divided the old notes on temperature into three parts:

Principle of the conservation of energy
Empirical observations of temperature (this part)
Energy and fundamental postulate

Our feeling of hotness comes from everyday experiences. These experiences indicate that many levels of hotness exist, and that all levels of hotness can be mapped to a real variable.

How can i model a crack in a solid block(3D) in ansys. Do i need to use quater point elements at the crack tip or a general mesh will be sufficient.?

i am working on composite risers and it has inner steel liner and carbon epoxy layers ,where there are 19 layers with 88 and 0 degree orientation alternatively. plss help me in modeling it.

1) i have assumed nu12 =nu23 for transverse isotropy case. i needed engineering constants to give as material properties. am i right???

2)how to create local coordinate system and assign it material orintation.
