Traditionally, the detection of the creep responses has been carried out using empirical
methods containing multiple adjustable parameters. This makes it very difficult to estimate …

Important advances in creep damage models for crack growth analysis have been made in
the last two decades as scientists and engineers strive to imbue continuum-based models …

The last few decades have witnessed an increasing emphasis on the development of strain-
based approach for predicting the creep life or damage of components operating at elevated …

The paper provides an advanced creep model which gives reasonable descriptions of the
effects of damage and stress state from micromechanics viewpoint. A modified creep ductility …

A unified constitutive model (UCM) coupled with a continuum damage model (CDM) is
developed to design and evaluate high-temperature components in the energy, aerospace …

In the present work, elasto-plastic creep crack growth simulations are performed using
