Hi 

I would like to know if anyone has any knowledge about using INISTATE command, As I am trying to use it to insert an initial stress state but which varies spatially

Hi tnegem,

You can check out the example for INISTATE in ANSYS. It located at: 

ANSYS Help Documentation-->Mechanical APDL-->Advance Analysis Guide

Chapter 5: Initial State

5.6. Example Problems Using Initial State

5.6.2. Example: Initial Stress (INISTATE Command)

From where I can get ANSYS Help Documentation. can you share the link please?

On the Start Menu under the ANSYS Folder is ANSYS Help.

In Workbench, there is a Help menu.

In Mechancial, there is a ? icon on the top right corner.

I have a layered structure like this. Suppose I have to give an initial state strain value to one of the layer. How I have to write the command.

When I wrote

inis,set,dtype,epel

inis,set,csys,0

inis,defi,,,,,

 

It gave the value to all layers. Any one please help me to rectify the issue.

For the above question, I gave 

solid1"_sid     in the geometry section of the above solid as command and gave the following command

 

inis,set,csys,-2

inis,set,mat,matid

inis,set,dtype,epel

inis,defi,,,,,-1.363e-3,-1.3063e-3,4.9759e-3,-1.363e-3,-1.3063e-3,4.9759e-3,-1.363e-3,-1.3063e-3,4.9759e-3

 

so it selected applied the strain value to top solid. If I have to assign a different strain to the second body ; how can I do this?

You can drag this command object from under the first solid and drop it on the second solid and the third solid, then each body will have a command object under it. They are each independent so you can edit each one.
