This French-language volume offers a comprehensive collection of 120 problems focused on elastic‑plastic fracture mechanics. Designed for students and professionals in mechanical engineering, the exercises guide readers through the analysis of stress, strain, and crack propagation in materials that exhibit both elastic and plastic behavior. Each problem is accompanied by detailed solutions that illustrate the application of fundamental principles and advanced techniques, making the book a valuable resource for coursework, exam preparation, and self‑study. With over 600 pages of carefully structured material, the work serves both as a practice workbook and a reference guide for those seeking to deepen their understanding of fracture mechanics in engineering contexts.
