Micromechanics of Lamina

This course covers the comprehensive study of micromechanics of lamina, a heterogeneous material composed of fibers and matrix. It begins with an introduction to micromechanics, explaining its significance in estimating the properties of lamina based on its constituents. The course further explores the concept of volume fraction and the mechanics of material approach. It then delves into the determination of engineering constants such as longitudinal Young's modulus, transverse Young's modulus, portions ratio, and Shear modulus. The course also highlights the limitations of the mechanics of material approach and introduces more accurate procedures like numerical and elasticity approaches. It concludes with a detailed discussion on the determination of strength properties of a unidirectional lamina using micro-mechanical approaches.
