Creep Deformation and Crack Growth Analysis of High Temperature Components

18th November 2020 - 09:30-12:30 GMT

The engineering components operating at high temperatures are subjected to time-dependent damage mechanisms, particularly creep deformation and crack growth. Due to the significant costs involved in fabrication and inspection of high temperature components it is desirable to optimise their lifetimes while ensuring that the aged components can sustain the applied loads with suitable safety margins against failure. Therefore, there is an essential need to accurately predict the remaining life of these components by considering the material deformation and damage evolution behaviour.

This workshop is designed to give engineers a more rounded appreciation of the unique considerations that should be given to the structural integrity assessment of high temperature components particularly in the power plants and jet engines. Several areas will be covered leaving delegates with a more rounded appreciation of the creep deformation, creep crack initiation and creep crack growth issues relevant to the components operating at elevated temperatures. Throughout the course, practical considerations will be used to consolidate the knowledge gained by the attendees and gauge their understanding.

The topics that will be covered in this webinar are:

​An introduction to time-dependent creep deformation
Characterisation of uniaxial creep properties for engineering materials
Elastic-Plastic-Creep fracture mechanics
Analysis of creep crack initiation and creep crack growth
Predictive models to assess the cracking behaviour of high temperature components
