Fracture Based Testing and Modelling,and Component Life Assessment of Welds
Fracture mechanics based methodologies are an important area of research that benefit life assessment techniques in components operating at elevated temperatures.There are many factors which determine a successful methodology for remaining life assessment of engineering components.Important elements are good testing techniques,the development of appropriate and accurate correlating parameters to treat the results in a the unified and verifiable manner in order to produce ‘benchmark material crack growth properties and developing accurate modelling procedures for life assessment methods.This presentation considers the first two aspects and identifies future trends and improvements in the developments of standardisations in creep and creep/fatigue crack growth testing of weldments containing residual stress.The paper highlights the important points in these pre-standardisation collaborative efforts by presenting the methods of analyses and example of their application to feature type components.
