Mécanique élastoplastique de la rupture is a comprehensive French treatise on the mechanics of rupture in elastoplastic materials, first published in 1989 by CEPADUES. Spanning 501 pages, the book delves into the theoretical foundations of stress–strain behavior, failure criteria, and energy dissipation in metals and polymers. It combines rigorous analytical derivations with practical examples, making it a valuable resource for researchers and engineers in materials science, structural mechanics, and fracture mechanics. The text is written in French and includes detailed tables, diagrams, and case studies that illustrate the application of elastoplastic theory to real‑world problems. Its depth and breadth have made it a reference point for subsequent studies in the field of mechanical failure analysis.
