| Abstract | In plane stress analysis the non zero components of stress tensor, and the respective components of strain, are related by the ortothropic stiffness matrix D. Its rank is equal to 3 and D is defined by the Young modulus in the vertical and horizontal direction (E^ and E2), the Poisson ratio v\i and the shear modulus G\I. The evaluation of the stress follows a Predictor-Corrector scheme: Prediction: Correction: in which er° is the initial stress, cr* represents the predicted stress, o is the corrected stress, AE is the total strain increment and A£J the variation of its inelastic part (unknown). Inelastic strains occur only when eq. (1) is violated by the predicted stress. The eq. (1) can be rewritten for the fc-th plane as: where n* is the normal to the plane and r* the distance between the plane and the origin at the beginning of the analysis step. The predicted stress er* can stay outside of one or more planes. If more than one plane has been violated by the predicted stress |
