Composite StructuresAbstract
Several studies showed that thin-plies composite laminates apparently exhibit higher strength than its counterpart using thicker plies. In this work, a high-resolution numerical discretization based on the use of in-plane-out-of-plane separated representations within the Proper Generalized Decomposition PGD framework is performed in di erent composites laminates for determining the e ect of ply-thickness on the laminate sti ness. The results reveal that the global sti ness increases with the ply-thickness reduction. The analysis also reveals that this mechanical enhancement is due to structural e ects and not to the mechanical con nement initially advanced.

When addressing the flow of concentrated suspensions composed of rods, dense clusters are observed. Thus, the adequate modelling and simulation of such a flow requires addressing the kinematics of these dense clusters and ... -
