Interfacial Mechanics of Offshore Engineering Equipment

This book is written based on a systematic and in-depth study on interface mechanics issues in marine engineering structures and equipment. It begins by establishing an accurate analysis model for the stress field at the interface crack tip, summarizing fundamental interface problems for any combination of two materials. It focuses on interface strength in defective marine metal composite and structures and proposes relevant strength analysis models and asymptotic damage mechanism of composite material pipelines and joint interfaces. An exploration for the mechanism of strength evolution and attenuation under complex ocean conditions is made, and the dynamic prediction for ultimate bearing capacity considering the strength attenuation of material and interface is given, and a detection method for interface damage of composite pipe cables is proposed. With combined method of theoretical analysis, numerical simulation and experimental verification, it provides valuable knowledge and practical techniques that can be applied in emerging marine engineering area. Researchers and engineers in the field of offshore engineering equipment can benefit from the book.

Offers systematic and comprehensive research results of composite materials in the field of marine equipment for readers Presents useful methodologies and measurements in design and safety assessment of marine composite structure Provides theoretical support and technical guidance in material selection design, service processing
