A Generalized Plane Stress Theory of Microstructure for Angle-Ply Laminates.
Abstract
A two-dimensional continuum theory of microstructure is developed for stress analysis of angle-ply laminates under in-plane loading. An example problem is used to evaluate the results of the theory against a reference solution obtained by the finite element method. The results are in satisfactory agreement; they also show that the in-plane stresses reach considerably higher peak values than reported in previous literature. The theory is also presented in a simplified version, which is demonstrated to be adequate for predicting interlaminar stresses and in-plane stress resultants, but does not give satisfactory results for the variation of in-plane stresses through the thickness of the laminations.
