The general case of loading N2 - Presents a new physical and mathematical theory of irreversible deformations and ductile fracture of metals that acknowledges the continuous change in the structure of materials during deformation and the accumulation of deformation damage. Plastic deformation, viscous destruction, evolution of structure, creep processes, and long-term strength of metals and stress relaxation are described in the framework of a unified approach and model. The author then expands this into a mathematical model for determining the mechanical characteristics of quasi-samples of standard mechanical properties in deformed semi-finished products UR - https://www.taylorfrancis.com/books/9780429259791 UR - http://www.oclc.org/content/dam/oclc/forms/terms/vbrl-201703.pdf ER -
