材料力學

This course provides a foundation of solid mechanics with applications to science and engineering. The main objective is to determine the stress, strain, and deformation of solids and structures withstanding forces. The theories are established on three fundamental concepts, including equilibrium, geometry of deformation, and material behavior.
