Controlling fatigue crack paths for crack surface marking and growth investigations

S. Barter, P. White, M. Burchill

While it is well known that fatigue crack growth in metals that display confined slip, such as high strength aluminium alloys, develop crack paths that are responsive to the loading direction and the local microstructural orientation, it…

Experimental investigation of the influence of internal defects (voids, wrinkles) on the shear properties of CFRP

Stanislav Slovikov, Dmitriy Lobanov

The study focuses on examining the impact of internal manufacturing defects (voids and wrinkles) on the mechanical behavior of structural carbon fiber reinforced polymers (CFRP) under shear loading. Specimens of VKU/VSE1212 material with a…

Generalised fracture mechanics approach to the interfacial failure analysis of a bonded steel-concrete joint

Wouter De Corte, Peter Helincks, Veerle Boel, Jan Klusak, Stanislav Seitl, Geert De Schutter

Steel-concrete joints are often made by welded shear studs. However, this connection reduces the fatigue strength, especially in situations where locally concentrated loads occur with a large number of load cycles e.g. in bridge decks. In…
