WebJan 12, 2024 · The focus is on unidirectional lamina which can be described based on orthotropic constitutive equations. Three classical approaches to predict the elastic properties, i.e., the mechanics of materials approach, the elasticity solutions with contiguity after Tsai, and the Halpin–Tsai relationships, are presented. WebMay 9, 2024 · In this analytical mechanics of material (MOM) model was developed to predict effective properties of the composite while numerical finite element (FE) model developed with the help of a representative volume element (RVE). Also, the longitudinal and transverse modulus of GRNC is determined using the Halpin-Tsai equations.
