This book thoroughly describes a theory concerning the yield and failure of materials under multi-axial stresses - the Unified Strength Theory, which was first proposed by the author and has been frequently quoted since. It provides a system of yield and failure criteria adopted for most materials, from metals to rocks, concretes, soils, and polymers. This new edition includes six additional chapters: General behavior of Strength theory function; Visualization of the Unified Strength Theory; Equivalent Stress of the UST and Comparisons with other criteria; Economic Signification of the UST; General form of failure criterion; Beauty of Strength Theories. It is intended for researchers and graduate students in various fields, including engineering mechanics, material mechanics, plasticity, soil mechanics, rock mechanics, mechanics of metallic materials and civil engineering, hydraulic engineering, geotechnical engineering, mechanical engineering and military engineering.
"The treatise with its systematic and integrated approach to the strength design of various engineering structures under the complex stress state is competently written by an author who with his associates has made some notable contributions. ... The book presents an important contribution to the field and is highly recommended to graduate students, engineers and researchers interested in the mechanics of the failure of materials." (M. Cengiz Dökmeci, zbMATH 1403.74003, 2019)
