Costas Soutis

TL;DR: Soutis et al. as mentioned in this paper examined the compressive behavior of bonded external patch repairs and showed that compressive loading mode is more severe than tensile mode owing to the instability of delaminated plies, instability of the patch and skin strength reductions occurring under elevated temperatures and absorbed moisture conditions.

TL;DR: Fan and Zhang as mentioned in this paper proposed the equivalent constraint model (ECM) to predict the effect of matrix cracking on the in-plane stiffness properties of composite laminates loaded in tension.

TL;DR: In this paper, a review of composite materials and finite element analysis is presented, focusing on composites and finite elements applied to composite materials, and the application of finite elements in composite materials.

TL;DR: In this paper, the authors summarized recent theoretical modelling developed by the authors on stiffness property degradation and mechanical behaviour of general symmetric laminates with off-axis ply cracks and crack-induced delaminations and derived closed-form analytical expressions for Mode I, Mode II and total strain energy release rates associated with these damage modes.

TL;DR: The feasibility of employing piezoelectric devices for the development of smart structures, where a small and lightweight transducer system design is required, has been demonstrated and the resonance spectrum method has been proposed as a technique for measuring the A0 Lamb mode phase velocity.
