Course description
Compositing materials is one of the most powerful methods of material development, and many composite materials have been developed. Mechanical properties of composite materials, such as Young's modulus and tensile strength, can be calculated from the mechanical properties of the base materials. In other words, composite materials can be designed based on mechanics of materials. In this lecture, the theory of elasto-plasticity and strength prediction based on the elasto-plasticity will be explained in order to design composite materials. In addition, rules of mixture, mechanics of anisotropic materials, and lamination theory, will be explained.
Purpose of class
Materials is important intechnologies related to machanical engineering, material development is necessary for the realization of innovative technologies. Materials design based on the mechanics of materials is one of the most important methods for the material development. Therefore, the purpose of this course is to understand the elasticity and plasticity theories, and to understand the basic concepts for the mechanical design of composites.
Goals and objectives
  1. Understanding the concept of mechanics of materials and elasticity.
  2. Understanding the concept of plasticity and the failure rule based on the plasticity.
  3. Understanding the mechanical design of composite materials based on mechanics of materials.
