FITNET

This is the second worked example in the [[FITNET|FITNET]] FAD example collection (§13.2.6, SSTP10). Its focus differs from the [[bs7910-a533b-residual-stress-fad|first A533B example]]: this time it is a welded stainless-steel wide plate with a through-thickness crack, assessed for ductile tearing (the crack grows stably as the load rises) on the FAD. We follow the [[bs7910-a533b-residual-kis-annexm|usual routine]] — run it in mechCalc’s BS 7910 Clause 7 fracture assessment calculator, read the chart, and cross-check point by point against the FITNET literature. ...

In the fracture-mechanics and fitness-for-service (FFS) literature, FITNET is a name you cannot avoid. Many large-component fracture-test examples, and many assessment results cited for cross-checking, are marked “from FITNET”. What is it, where did it come from, and why is it authoritative? This article sets it out from public sources. 1. In one line: what FITNET is FITNET (European Fitness-for-Service Network) is an EU-funded research collaboration network. Its goal is one sentence: to establish a unified, validated fitness-for-service procedure for flawed metal structures (welded and non-welded) — the later FITNET FFS Procedure. ...
