Hi,
Depends on type of material whether it is ductile or britle.

Hi Prakash,
My material is Aluminium with material properties :
Ultimate Tensile Strength : 296 MPa
Yield Strength : 145 MPa
Poisson ratio : 0.33
Density : 2.66 gr/cc

The stress is near the ultimate tensile strength. Maybe you should carry a material non linear analysis.

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,

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.

Thank you for your guidance,
From stress-strain curve there are a lot of value that can be used to fulfill the X & Y, I mean in which position of stress-strain curve should be used? (see the attachment)
Thank you & regards,

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.
