Properties and mechanics of fibrous, laminated composites. Classical lamination theory, micromechanics, stiffness and strength, fabrication and testing. Thermal stresses. Design, analysis, and computerized implementation.
Specific Course Objectives :
Describe the processes by which the constituents of laminated composite materials and the composites are manufactured.
Describe the basic stress-strain behaviors of fibrous composite materials having different orientations, as well as the test methods utilized to determine these behaviors.
Use micromechnical models to estimate effective engineering properties (stiffness and expansional coefficients) in terms of fiber and matrix properties, as well as fiber volume fraction.
Explain the assumptions employed in the classical lamination theory. (CLT)
Use a computer code that you develop to calculate the loading required to achieve a prescribed strain field including prescribed moisture and temperature conditions and to use the same computer cords to determine the strains resulting from specified applied loads.
Compare and contrast failure theories for in-plane loading of composite materials. Use these failure criteria to predict first-ply failure of composite laminates. Apply discount theory to estimate ultimate loads of composite laminates.
Design composite parts based up specified stiffness and/or strength requirements.
