A model to predict stiffness is then established based on the stiffness volume average method and on the laminatedplatetheory by assuming that differential yarns are straight.
然后建立模型预测刚度刚度体积平均方法和基于层压板理论假设，差别化纱线是直的。

A refined theory of laminatedplate is presented, and the analytical solutions of thick laminated composite plates are given for two particular laminates under associated boundary conditions.
On the basis of classical lamination theory and large deflection hypotheses of plate, the equilibrium and compatibility equations of simply supported composite laminated plates were obtained.
