Unified Strength Theory and Its Applications

Yu Mao-Hong is a Professor at Xi'an Jiao Tong University, China. He has been studying the strength theory of materials and structures for a long time since he graduated from Zhejiang University in 1955. He proposed the Twin-shear Yield Criterion for metals, the Twin-shear Strength Theory for geo-materials and the Unified Strength Theory for different kinds of materials for metals(1961)/for geo-materials(1985)/for different kinds of materials(1991). The twin shear unified strength theory has been written into more than 300 monographs and textbooks.

Yu Mao-Hong is the winner of the National Natural Science Price of China and the winner of the Ho Leung Ho Lee Foundation Mechanics Prize. His research areas focus on Mechanics of Materials, Plasticity, Structural Mechanics, non-linear FEM, Soil Mechanics and Rock Mechanics.

Yu Mao-Hong has already published the followed monographs with Springer:

1. Unified Strength Theory and Its Applications (2004)
2. Generalized Plasticity (2006)
   
3. Structural Plasticity: Limit, Shakedown and Dynamic Plastic Analyses of Structures (2009)
   
4. Computational Plasticity: With Emphasis on the Application of the Unified Strength Theory (2012)
   

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.
