3 0 0 3
OBJECTIVE
i) To understand the fundamentals of composite material strength and its
mechanical behavior
ii) Understanding the analysis of fiber reinforced Laminate design for different
Combinations of plies with different orientations of the fiber.
iii) Thermo-mechanical behavior and study of residual stresses in Laminates
during processing.
iv) Implementation of Classical Laminate Theory (CLT) to study and analysis
for residual stresses in an isotropic layered structure such as electronic
chips.
