heal.abstract	A theoretical model is proposed to predict the limit strains and the forming-limit diagrams both in the first (I) and in the second (II) quadrants of the strain locus of thin sheets subjected to biaxial stretching. Based on the Marciniak-Kuczynski model and employing the non-quadratic m-yield criterion, the proposed model also correlates surface integrity changes resulting from mechanical processing; either low-speed directional rolling or stochastic ball-drop forming and thermal stochastic electro-discharge machining. Theoretical predictions and experimental data from previous work are compared and the suitability of the theoretical model in studying the deformation behaviour in sheet metal forming is discussed. © 1991.	en
