Abstract Macroscale cleavage fracture toughness of high strength steels is strongly related to the hard microstructural inclusions. Therefore, an accurate determination local stress on these inclusions based matrix necessary for statistical modelling macroscale fracture. This paper presents analytical equations quantitatively estimate from far-field matrix. The account inclusion shape, orientat...

Multi-layered systems used in automotive plain bearings show complex patterns of crack growth under service conditions. The studied architecture consists of a steel backing (1.8 mm), a compliant pure-aluminum interlayer (0.04 mm) and a lining of medium-strength aluminum alloy (0.38 mm). Previous experimental studies [1] with flat strip specimens of identical architecture under three point bendi...

offshore pipelines are an effective tool for transportation of oil and gas which are usually assembled by the use of girth welds. since flaws may naturally exist at such welds, fracture assessment of girth welded offshore pipelines is substantial. current fracture assessment procedures like bs 7910 consider identical material properties for the weld and the base metals. however the strength dif...
