WebThe null stress (s33 = 0) and incompressibility (J = 1) conditions in finite strain elasto-plastic shell analysis are studied in closed-form and implemented with a variant of the combined control by Ritto-Corrêa and Camotim. Coupling between constitutive laws and shell kinematics results from the satisfaction of either of the conditions; nonlocality … WebA further key aspect of any theory of plasticity, and in particular of a finite-strain theory, is the form taken by the evolution equation or flow law.
