Mechanics of Composite Materials


Spring 2018

Days/Time: MWF / 11:30 am-12:20 pm
Credit Hours: 3

Learning Objective:
To introduce modern composite materials and their applications and to build proper background for stress and strength analysis in the design of composite materials and structures. At the end of this course, student should be able to: Describe the characteristics and the manufacturing principles of composite laminates. Carry out thermoelastic analyses for the determination of the stress and strain state in a multi-axial laminate subjected to inplane and bending resultants. Predict the strength of multi-axial laminates. Carry out interlaminar fracture calculations for unidirectional laminates. Understand the bending-twisting-extensional coupling in symmetric and unsymmetric laminates. Determine the stress state at the free-edge of a finite-width laminate.

This course provides students a background in modern composite materials which are being used in an ever-increasing range of applications and industries. Basic knowledge of composite materials will allow engineers to understand the issues associated with using these materials, as well as gain insight into how their usage differs from conventional materials such as metals, and ultimately be able to use composites to their fullest potential. Topics covered include: current and potential applications of composite materials, fibers, matrices, manufacturing methods for composites, anisotropic elasticity, micromechanics for determining mechanical properties of composite materials, classical laminated plate theory, free-edge stress analysis, and failure analysis of composite materials.
