Abstract
A method of analysing the creep behaviour of cylinders, spheres and thin discs is described, in which the effects of time variation of the environmental conditions of temperature, pressure, rotational speed and internal heat generation may be accommodated.
Deformation is considered as a series of steps each consisting of a short period of steady state creep followed by instantaneous stress readjustment to resatisfy the equations of equilibrium and compatibility. The relationships for stress readjustment can be written down once for all, since they are independent of the type of creep law used and of the length of time interval taken. The simultaneous solution of these relationships is presented in a form suitable for incorporation in computer programmes.
