A Dimensionless Analysis of Stress Distribution for Hydrostatic Tension in an Orthotropic Plate

Hsien-Liang Yeh*

The effect of lamina material properties on the stress distribution of the orthotropic composite plate containing a circular cutout under hydrostatic tension is investigated. Based on the generalized Hooke’s law, the generalized 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 cutout in the composite plate under hydrostatic tension. 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.
