The basics of structural calculation using mechanical properties, which are important properties among the physical properties
of materials, and the theoretical background of the mechanical properties of materials are deepened from the viewpoint of
material engineering such as crystal structure. In Material Mechanics B, using the stress, strain, and elastic modulus learned
in Material Mechanics A, practice strength calculations in beams and more complex three-dimensional states, and learn about
the stress states of materials beyond the elastic range.
Elastic properties of materials and their application to calculate strength of simple shape structures.
Understanding of materials selection method using elastic properties of materials.
Acquire the ability to understand the plastic properties of materials and their physical meanings.
