A substantial amount of research effort has been applied to the field environmentally assisted fatigue (EAF) due requirement account for EAF behaviour metals existing and new build nuclear power plants. We present results European project INcreasing Safety in NPPs by Covering Gaps Environmental Fatigue Assessment (INCEFA-PLUS), during which sensitivities strain range, environment, surface roughness, mean hold times, as well their interactions on life austenitic steels characterized. The...
INCEFA-PLUS stands for INcreasing safety in nuclear power plants by Covering gaps Environmental Fatigue Assessment. It is a five year project supported the European Commission HORIZON2020 program that commenced mid-2015 and which sixteen organizations from across Europe participate. Specifically, effects of mean strain/stress, hold time, strain amplitude surface finish on fatigue life austenitic stainless steels light water reactor environments are being studied, these issues common interest...
Abstract INCEFA-SCALE is a five-year project supported by the European Commission HORIZON 2020 programme. kicked off in October and successor to INCEFA-PLUS programme that ran from 2015 2020. The objective continue working towards advancing ability predict lifetimes of Nuclear Plant components when subjected Environmentally Assisted Fatigue (EAF) loading. operators have generally observed number failure events attributable EAF are fewer than predicted current assessment methodologies. It...
This paper presents an analysis of the notch effect in fracture micromechanisms. To this end, experimental results obtained notched specimens are presented, together with corresponding stress field at and SEM fractographies. The comprise three materials (structural steel S275JR, high-strength aluminum alloy Al7075-T651 Polymethyl methacrylate-PMMA) radii varying from 0 mm (cracks) up to 2.5 mm. show how relaxation caused by is accompanied a progressive change mechanisms, basically brittle...
INCENFA-SCALE is a five-year project funded by the EC Horizon2020 programme, successor of INCEFA-PLUS project. INCEFA-SCALE started in October 2020. The objective this to improve capacity predict lifetime Nuclear Power Plant (NPP) components subjected environmental assisted fatigue. starts off analysing existing data and then provides new environmentally fatigue which allow laboratory test outcomes be applied with real geometries loads. So far, mining different finished projects...
Abstract The European project INCEFA-PLUS characterises environmentally assisted fatigue in light water reactor conditions. aims at developing a new procedure to assess damage susceptibility nuclear power plant components. basis for the development of assessment is major test campaign carried out eleven different laboratories across Europe which will deliver approximately 200 tests. based on common matrix that was optimized by means Design Experiments method. initial focus effects and...
Nowadays, environmental fatigue assessment is mandatory in many countries, the design and operational stages of nuclear structural components. The analysis can be a complex engineering process that generally performed following national or international procedures. Such procedures are not always based on same assumptions, novel analysts may find confusing variety documents. Moreover, once specific procedure has been chosen for analysis, it possible to complete by using transients (and loads)...
Abstract The European Project INCEFA-PLUS (INcreasing Safety in NPPs by Covering gaps Environmental Fatigue Assessment) characterizes environmentally assisted fatigue of stainless steels light water reactor environments. project includes a major test programme during which more than 200 tests have been carried out different laboratories across Europe. campaign was structured three successive phases with slightly foci. All testing programmes were optimized means the Design Experiment method....

INCEFA-PLUS (INcreasing Safety in NPPs byCovering gaps Environmental Fatigue Assessment) project characterized environmentally assisted fatigue of stainless steels light water reactor environments.During this more than 200 tests have been carried out different laboratories across Europe air and environment.Most were performed on a single batch 304L, an austenitic steel alloys employed NPPs.The addressed the effects strain amplitude, hold time periods, material roughness mean strain/stress...
This paper analyzes a novel solution of dental prosthesis containing gold washer between the implant and screw head (made titanium alloy, Ti-6Al-4V), compares its mechanical behavior under variable loading with those observed in two other solutions commonly used dentistry, one them having implant, abutment made pure (the being same alloy). The analysis has consisted measurement torque loss three types prostheses after application given number cycles following ISO protocol 14 801....
