Mechanics of Materials (Thirteenth Five-Year Plan Textbook for Civil Engineering and Transportation in General Higher Education)

This textbook analyzes the internal force analysis under basic deformation forms, the derivation of stress calculation formulas, and their applicable conditionality. It also gradually introduces concepts and methods such as unit bodies, stress states, and simple superstatic determination, and applies them through examples and exercises to achieve the effect of repeated consolidation. The textbook includes introduction, axial tension and compression, shear and extrusion, torsion, bending internal force, bending stress, bending deformation, stress state analysis, strength theory, combined deformation, pressure bar stability, dynamic load and appendices. This textbook is for teaching in civil engineering, machinery and other related majors in colleges and universities, and can also be used as a reference for professional practitioners.
