Impact of Uncertainties on Structures Damage Tolerance Parameters
… Traditional fracture control methods, such as damage tolerance analysis (DTA), assume deterministic factors, considering uncertainties inherent in material properties, inspections, and operational conditions only at the final stage by applying safety factors. This research seeks to incorporate …

Finite element modelling of fatigue crack growth in multi-layered architectures
… step extensions to account for crack growth. The analysis of forecasted paths for deflected and bifurcated cracks showed the tendency of the crack to grow parallel to the layers orientation within the compliant interlayer, as observed experimentally, and following a path which maximised the crack …

Refined theories and Discontinuous Galerkin methods for the analysis of multilayered composite structures
… to environmental and inter-laminar damage effects. One of the key aspects of the analysis of composite structures is the accurate prediction of the stress field; it can be obtained employing several numerical methods that can provide very detailed results at an high computational …

Multidisciplinary Optimization and Damage Tolerance of Stiffened Structures
… application scaling with medium fidelity FEM analysis. Both the global wing design variables and local panel design variables are optimized to minimize the wing weight at an acceptable computational cost. The structural weight of the wing has been, therefore, reduced by 40% and the parallel …
