Micromechanics of a Unidirectional Fiber-Reinforced Composite Layer Lamina

1 Micromechanics of a Unidirectional Fiber-Reinforced Composite Layer (Lamina) 

The objective of micromechanics analysis is to determine Ihe elastic moduli (slifi iess and compliance) of a composite material in terms of the elastic moduli of the constituent 

The mechanics of materials approach is taken in developing micromechanical relationships between constituent and composite material properties. The basic assumptions inherent in this approach are the following  

The fibers are homogeneous, linearly elastic, isotropic, regularly spaced, and perfectly aligned 

The lamina is considered macroscopicaUy homogeneous and orthotropic, linearly elastic, and initially stress free
