Strengthening Mechanisms in Metals/Alloysations. These challenging technological environments demand controlled strengthening of alloys by using appropriate strengthening mechanisms. This chapter first introduces the significance of dislocation motions in strengthening of a metal/alloy. Then various strengthening mechanisms have been discu矛盾心理 发表于 2025-3-26 02:34:48
Materials in Engineering into four basic categories: (1) metals/alloys, (2) polymers/plastics, (3) glasses and ceramics, and (4) composites. Both ferrous metals and non-ferrous metals are discussed with reference to their characteristics, mechanical behaviors, and applications. Cast irons and their types are explained bothBRIDE 发表于 2025-3-26 06:04:25

Elasticity and Viscoelasticityships between ., ., and .. A distinction between isotropic and anisotropic materials is made. The elastic properties . and . are explained and mathematically modeled. The Hook’s law is generalized to take into consideration stresses and strains in three dimensions. A workable expression for the bulkPruritus 发表于 2025-3-26 13:05:33
Complex/Principal Stresses and Strainshnological significance is emphasized. Then the state of plane stress (both in 2D and 3D) is introduced with reference to principal stresses. The direct and shear stresses have been analyzed so as to derive mathematical models to calculate the stresses. Additionally, mathematical relationships for t配置 发表于 2025-3-26 18:55:12
Plasticity and Superplasticity – by discussing stress-strain curve for mild steel. The main topics include: plastic instability and the mathematical analysis of the condition of plastic instability; the .; bending of beam, its applications, and engineering analysis; the application of plasticity to sheet metal forming; hydrostatic
