    Hello,

    I will work on a project as a student in my university. I need to perform some ANSYS analyses with some polymers. As you know, I need to enter the mechanical properties of the material into ANSYS.

    I found the website matweb.com and look for the material "165 H Polystyrene"
    I could enter only the Density, Isotropic Elasticity, Tensile Ultimate Strength. I couldn't find where to enter the other values (mechanical properties). So, now I am not sure if these 3 properties are enough for a stress analysis. I know that matweb.com has a premium membership and it gives an Ansys ready engineering data file. Has anyone tried that? Or can anyone tell me that if these three properties are enough? I want to see what the premium membership available file has but the membership is $100/year (which is a little too much for this one time project)

    thank you

    refer to ansys help option . Ansys has a very good help command with itself..

    Depends on which failure mode you are looking at.
    If you are happy with brittle fracture (which the foam materials usually observe), UTS should do.

    I usually compare max principal stress with Ult Tensile Stress and min princ stress with ult compressive stress for brittle failure. But usually UCS / bending comp stress is lower than UTS
