  In this paper, we use isogeometric Kirchhoff plates to approximate composite
laminates adopting the classical laminate plate theory. Both isogeometric
Galerkin and collocation formulations are considered. Within this framework,
interlaminar stresses are recovered through an effective post-processing
technique based on the direct imposition of equilibrium in strong form, relying
on the accuracy and the higher continuity typically granted by isogeometric
discretizations. The effectiveness of the proposed approach is proven by
extensive numerical tests.
