ETD has launched a new proposal for a Group Sponsored Project. The proposal is entitled ‘CRACKFIT – Defect Assessment Tool for Boilers/Pressure Vessels & Turbines’.
Crackfit© is the ETD’s commercial procedure and software for assessing cracks in pressure vessels, piping and standard fracture mechanics specimens, both at low and high temperature. It is based on the prototype initially developed with the support of the European Commission and European industry. The commercial version was developed by ETD as a joint venture in collaboration with the European industry and independently verified by experts. Crackfit carries out crack and life assessment both deterministically and probabilistically - probably the most advanced procedure for probabilistic crack assessment. Crackfit significantly reduces the time required to carry out assessment, in some cases from weeks to days! Crackfit comes with an optional crack initiation and growth database for base metal, HAZ and welds and for many materials of interest to industry. It deals with defects such as lack of fusion / penetration in welds (defects at weld toes), internal and external surface emerging or embedded defects in straight pipes and pipe bends, defects at stress concentrations such as sharp corners (T-pieces, nozzles), defects in plates etc.
The software is user friendly for industry engineers who would like to carry out defect assessments without having to go through the different established codes or country / in-house defect assessment practices. Procedures including BS7910, the French code RCC-MR A16 and the European procedure ‘HIDA’ are available as software options. The software allows for failure analysis (fast fracture, plastic collapse and ligament rupture) and the evaluation of damage mechanisms such as creep, fatigue, and creep-fatigue interaction.
