Abstract

Analytical solutions are sought for optimal temperature distributions to control interlaminar stresses near the free edges of composite laminates subjected to uniaxial loading. Thermal gradients are obtained by minimizing appropriate performance indices that are functions of the far field properties with respect to the through thickness temperature differences. It is shown that a uniform temperature drop or rise can completely eliminate all of the interlaminar stresses for cross or angle ply laminates and for other laminates, nonuniform temperature distributions must be applied to minimize the stresses.
