i must do an analysis of a piece in which there is a geometric nonlinearity (large deformations). now i have the young modulus, the yeld stress, the tensile strenght and ather parameters but i need the tangent modulus because somehow i must define the nonlinear region...
bye
i use cosmos designstar and i'm doing a nonlinear analysis of a component made in CuZn30. I need the etan value (tangent modulus)of this material. can someone help me? and after do someone know an internet site where j can find this value for every steels and brass?
