27 As the resin matrix type is the same for all plies (and fiber material on its own has a limited effect on fracture toughness) it is these discontinuities rather than fracture mechanical differences between CFRP and GFRP (e.g., GIC and GIIC) that drive damage morphology. Fig. 13(c) ...
fracturepost-bucklingDICNDTThe present study analyses an aircraft composite fuselage structure manufactured by the Liquid Resin Infusion (LRI) process and subjected to a compressive load. LRI is based on the moulding of high performance composite parts by infusing liquid resin on dry fibres instead ...
Using the independently measured laminate parameters of compressive unnotched strength and in-plane fracture toughness the model predicts successfully the notched strength as a function of hole size and width.J.

Using scanning electron microscopy (SEM) and energy dispersive X-ray (EDX), it was inferred that the delamination fracture located within the ceramic coating close to the TBC/TGO interface. The results agree well with other experimental and theoretical results....
Introduction Since the first introduction by Leonhard Euler [1], the phenomenon of buckling, a mechanical instability leading to flexural fracture under high compressive stress, has been widely studied in regard to, for example, the compressibility of living cells [2], the bending and buckling of...
The description of fracture, buckling and post-buckling behaviour of composite struc- tures with delaminations can be carried out in two general ways: (1) a 3D approach— usually the finite element method; and (2) 2D analytical approximations. In the latter case, the form and the correctness...
2.6. Scanning Electron Microscopy In this study, a scanning electron microscope (SEM) was used for the characterization of fracture facies in order to visualize the different damages produced. As it is usually done with composite materials, the acceleration voltage of the beam used is equal to ...
