Evaluation of the common format for creep deformation

A common format is proposed which relates creep deformation equations to the equation formats found for elastic and plastic deformation. This common format gives a reproducible form for writing the relationships between load, deformation and geometry factors. The importance of this common format is that the equation forms used in elastic and plastic deformation can be used to develop the equations needed for creep deformation, thus making the development of some of the relationships used for the analysis of cracked body geometries in creep much simpler. The evaluation of a common forms of equations between creep deformation and elastic and plastic deformation is conducted experimentally and numerically in this paper. A compact specimen geometry is used as the model for both evaluations. The implications of this common format in developing relationships are also briefly discussed
