A dimensionless analysis of stress distribution for constrained pressure in an orthotropic plate

Abstract

The effect of the properties of lamina material on the stress distribution of the orthotropic composite plate containing a circular cut-out under constrained pressure is investigated. Based on the generalised Hooke's law, the generalised plane stress condition and the complex variable method, a dimensionless analysis is used to evaluate the influence of various elastic moduli E₁, E₂, G₁₂ and ν₁₂ on the stress distribution along the boundary of the cut-out in the composite plate under constrained pressure. The results obtained from this dimensionless analysis provide a set of general design guidelines for structural laminates with high precision requirements in the engineering applications.
