The effective through crack fracture toughness of structural components of older inhomogeneous steels
1995 (English)In: Materials ageing and component life extension: proceedings of an International Symposium on Materials Ageing and Component Life Extension, held in Milan, Italy, 10 - 13 October 1995 / [ed] V. Bicego, Warley: EMAS , 1995, p. 147-154Conference paper, Published paper (Refereed)
Abstract [en]

Older, ordinary structural steel sections are often inhomogeneous in their microstructure, having a low-toughness "core" material and a higher toughness surface material. The overall behaviour of such structural components has been found to be more ductile than predicted by "weakest-link" arguments. This behaviour is analysed by extending the theory of the globally elastic fracture of layered sandwich materials to accommodate non-linear behaviour and mixed toughness. The extended theory has been applied to the behaviour of full scale beams typical for bridges.
