    Hello sir, I have a question on example 1, condition 2. Does the variable sigma_VM change at every increment or does it stay constant in the equations?

      It changes. sigma_VM is function of sigma_11 and sigma_22 which are both increasing after initial yield.

      @@CivE_UoA thanks so much! I have another question on example 1, condition 3 (plane strain). In plane strain, can we apply Levy-Mises equation and use sigma_33 = 0.5*sigma_11 for the plastic regime equations in 21:50?

    Thank you for the great explanation. However I would like to ask you where we can use the plastic modulus "h" in terms of " E " and "E(tan)" as given by the expression, h= (E*E(tan)/(E-E(tan)) ? In your example your determined it directly as the slope of the straight line? Thank you

      Sorry, I don't understand your question.

      Sorry Dr@@Samer_Adeeb , iam new to plasticity of steel so that i might not set the question correctly . The plasticity modulus was determind here with value of 606.678 MPa as ratio of yeild stress to plastic strain. But i found in some books that the plastic modulus h =(Young Modulus*Tangential Modulus)/( Young Modulus-Tangential Modulus). My qustion is, can we use this expression of h given above interm of E and E_tangential in the determination of plastic modulus of istropic linear hardening . I hope you get what i mean by this question

      @@magedqasem7403 Yes, absolutely. Just be careful that the equation you listed is only applicable for a bilinear stress-strain curve.

    Sir can you suggest any relevant book on this concept?
