This course deals with anisotropic composites as structural materials. The students who want to take this course should have learned mechanics of materials and the basic concept of theory of elasticity. The composite materials dealt with in this course include anisotropic elastic modulus and anisotropic strength. The concept of design of the composite structures is the main theme of this course.
Composite materials are applied to aircrafts, automobiles and robots. As one of the advanced design tools after the conventional mechanics of materials, design of anisotropic materials is dealt with in this course.
In the designing of composite materials, designers cannot have published fixed material data. The composite materials have different properties when the components made from the composites are fabricated with different method. The designers have to pay attention to the factor of safety from the fabrication method of the composite components. In this course, students will familiar with the mechanics of anisotropic materials. For the carbon fiber reinforced composites, tensile strength is different from the compassion strength. The course deals with the design of these strongly anisotropic materials. In addition, design of plate buckling of anisotropic composite plate is dealt with in this class.
By the end of this course, students will be able to:
1) Understand the fabrication process of composites.
2) Learn how to deal with the safety factor for the large scatter composites
3) Learn the mechanics of materials of anisotropic materials
4) Learn the lamination theory
5) Acquire the structural design of composites

This calss will be graded by exam(40%) and assignments (60%).
All assignments have to be written in English.
Mechanics of materials must be taken. The basic of theory of elasticity has better be studied.
