This well-known and proven textbook on strength calculation brings together the fundamentals taught in mechanical engineering studies, covering materials science, mechanics, and machine elements. It is free from unnecessary ballast, clearly structured, and presents the essential strength issues in boiler, vessel, and piping construction in a concise manner. The author of the new edition has updated the work to the latest state of technology and expanded it with a chapter on the explosion resistance of equipment and pipelines, as well as a chapter on stress assessment of explosion pressure-resistant components. The book takes into account the new AD guidelines published since 1990, particularly regarding stress assessment. It serves as a valuable resource and guide for both practicing engineers and students in solving strength-related questions.
