    AISI 4130 - Tangent modulus

    Thanks sdm919 . I should have clarified. The Tangent modulus was for bilinear-idealization. So the second slope, after reaching the yield point is what I was referring to. SUMATECH, INC. www.sumacon.com

    Von Mis stresses for standard profiles, Wide flange sections, Channels, Angles, etc

    Von Mis stresses for plates & shells can be obtained in Staad. Is it possible to do so for standard profiles like angles, hollow sections, beams, etc? Staad provides combined stresses. Some codes use Von Mises stresses to specify permissible stresses.
