Dear Prakash,

 

Thank you for your response,

 

First, I would like to inform that I use optistruct solver to do the simulation, with MAT1 material card.

 

Actually, I only want to know about static stress on it, but the problem is when I set the value of stress legend, the red color show and I don't know the interpretation of that color.

 

So, I ask this to this forum.

 

regards,

Iron_Man

Hi @Iron_Man59,

 

1. What you are seeing is stress-strain curve which is a material property. You can get details of stress-strain curve for material from respective supplier or you can search for the on any material data base.

 

2. PFA, PDF- NLPARM parameters.

It again depends. If you are designing something to failure, use last point.

 

If you are designing till Yield point, then you need to use yield point value.
