Mechanics of Materials 2Nd Edition (The "14Th Five-Year Plan" Textbook for Civil Engineering and Transportation in General Higher Education)

Based on the first edition, this textbook adds new content that reflects the development of cutting-edge science and technology; incorporates new ideas that reflect the ideological and political aspects of the curriculum; and highlights basic concepts, basic theories, and basic methods. The content remains relatively independent from related courses without losing coherence and permeability. The selected examples and exercises are not only conducive to heuristic, guided and interactive teaching; they are also conducive to cultivating students' ability to analyze and solve problems and their ability to think innovatively. This textbook has 15 chapters in total, including the introduction and basic concepts, axial tension and axial compression, torsion, bending internal force, bending stress, bending deformation, simple statically indeterminate problems, stress state and strain state analysis, strength theory, combined deformation, strength calculation of connected parts, pressure rod stability, energy method, dynamic load and alternating stress and strength calculation of rods when considering material plasticity; the appendix includes the geometric properties of plane graphics and section dimensions of steel sections, section area, theoretical mass and section characteristics. This textbook can be used as a material mechanics textbook or reference book for engineering mechanics majors in colleges and universities, water conservancy, civil engineering majors and other majors; it can be used as a reference book for undergraduate mechanics competitions and master's entrance examinations; it can also be read and referenced by teachers and engineering technicians in mechanics and related majors.
