Fig. 1 Curve Fig.2 Curve In accordance with the Pairs Equation [1]: (4) Where: is the crest value of the stress intensity factor, C and m is the constant of materials.
With the increasing rate of crack growth, it goes up while the Constant C of the materials in the Pairs Equation becomes gradually smaller and Constant m increases.
The crack growth rate da/dN corresponding to different survival rates p goes up with the increasing rate of the survival rate, the Constant C of the materials in the Pairs Equation becomes gradually smaller and the Constant m increases.

Fig.1 The generalized Maxwell model Fig.2 Thermo-Rheologically Simple Behavior Viscoelastic materials are highly sensitive to temperature changes and characterized as Thermo-Rheologically Simple (TRS).
These materials exhibit an approximate translational shift of all the characteristics response functions without a change of shape along the logarithmic time axis as Fig.2 shows

For brittle material, the evolution of the interface Γo separating the undamaged material d = 0 to the damaged one d = 1 have been studied in a framework based on an energetical description ([4, 11]).
The initial material and the damaged material are separated by a surface Γo.

It is assumed that the plates are homogeneous and the thermal and elastic properties of materials are temperature independent.
However, the material properties are temperature dependent for many materials.
It is assumed that temperature varies across the plate thickness and the elastic, and thermal properties of material are functions of temperature, which will result in the inhomogeneity of materials and be considered in derivation of governing equations of the plates.
It is seen that the thermal postbuckling equilibrium path becomes significantly lower when the temperature dependent properties of materials are taken into consideration, and the effects of temperature dependent material properties increase significantly with increasing deflections.
