Damage mechanics approach for predicting material processing defects M. Predeleanu Laboratoire de Mecanique et Technologic E.N.S. de Cachan - CNRS - Universite Paris 6 France. Abstract Damage theory has been successfully introduced over the last two decades for predicting and avoiding the occurrence of defects in manufactured products. Advanced methods have been proposed to characterise the workability of a material and to estimate the resultant soundness of the manufactured products, obtained by different operations such as: deep drawing, forging, rolling, etc. The keynote lecture reviews the main damage models and significant applications in this field. 1 Introduction The occurrence of defects in manufactured products and, more appropriately, defect avoidance by limitation of material deformation and processing have always represented the main focus of all sectors of the manufacturing industry. The range of fabrication and material working defectiveness encompass: a) th
