Finite element parametric analysis is performed on a cracked bi-material bar subjected to pure bending in order investigate the fatigue behaviour of short crack thin protective layer laser-cladded steel substrate. Elastic properties surface are chosen with regard real combinations materials when bronze, nickel or cobalt alloys applied as layers improve basic substrate and influence their mismat...

Analytical integrations, in the framework of linear elastic problems modelled by means of boundary integral equations, have been considered in a previous publication (Int. J. Numer. Methods Eng. 2002; 53(7):1695–1719): the present note aims at extending the subject to linear elastic fracture mechanics. In such a context, special shape functions have been recently proposed (SIAM J. Appl. Math. 1...

In linear elastic fracture mechanics the stress and strain magnification at crack tip is characterized by intensity factors which have been obtained for a large variety of loading specimen geometries course mode II test included. this paper not only different kinds boundary conditions contact surfaces will be discussed but plastic one. The rotation center line also discussed. results show power...

This inaugural article has a twofold purpose: (i) to present a simpler and more general justification of the fundamental scaling laws of quasibrittle fracture, bridging the asymptotic behaviors of plasticity, linear elastic fracture mechanics, and Weibull statistical theory of brittle failure, and (ii) to give a broad but succinct overview of various applications and ramifications covering many...
