Non-destructive estimation of three-dimensional creep strain based on non-linear inverse analysis using displacement

In mechanical structures exposed to high temperatures, such as turbine blades for power generation, cracks are detected during in-service inspections. However, there is a risk of fracture owing to the relatively rapid rate of crack propagation, even when a large safety factor is in force. Therefore,...
