The present work focuses on reconstruction of the transverse normal-stress profile in finite element analysis of FSDT laminated plates. The reliability of this reconstruction depends on accuracy of second derivatives of the stress resultants, not guaranteed by most of available low order plate finite elements, so that the reconstructed stress profiles may even not converge with mesh refinement. To address this difficulty, two different reconstruction strategies, based on the Recovery by Compatibility in Patches procedure, are proposed and compared.

Abstract
The present work focuses on reconstruction of the transverse normal-stress profile in finite element analysis of FSDT laminated plates. The reliability of this reconstruction depends on accuracy of second derivatives of the stress resultants, not guaranteed by most of available low order plate finite elements, so that the reconstructed stress profiles may even not converge with mesh refinement. To address this difficulty, two different reconstruction strategies, based on the Recovery by Compatibility in Patches procedure, are proposed and compared.File in questo prodotto:
