Introduction,information is needed, how can it be generated? How can the information best be used in proposing alternative paths to achieving a useful and reliable end product? These are some of the questions a designer has to answer. In so doing, programmes of . research and development often have to be formula

Factors affecting strain accumulation,imensional changes with time, even of the order of a few millimetres, leading to mismatch of components or contact between moving parts, could lead to serious damage to plant, not to mention loss of human life and revenue. Such conditions must obviously be considered as a failure criterion, even tho

Extrapolation of creep strain and rupture data,it is considered satisfactory if a stress level can be specified below which there is no danger of rupture or excess deformation occurring during the life of the component. The common criteria by which creep strength is judged are follows.

Creep fracture,which cannot be evaluated entirely by continuum methods without taking into account the specific form of the local deviation. Problems involving crack-like defects therefore require a special analytical tool which includes the presence of the defect in the mathematical model. This tool is fracture m
