Mechanics of Composite Materials

AAE55500

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.

Description:
This course provides students a background in modern lightweight composite materials which are being used in an ever-increasing range of applications and industries. Basic knowledge of composites will allow engineers to understand the issues associated with using these materials, as well as gain insight into how their usage differs from 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, review of elasticity of anisotropic solids, methods for determining mechanical properties of heterogeneous materials, micromechanics of continuous and discontinuous fiber systems, laminated plate analysis, static analyses of laminated composites, edge effects in laminates and both macroscopic and microscopic failure analysis of composite materials and laminates.
