In resent years, thermo-gravimetric (TG) is widely used in the research of coal combustion and paralysis [1].TG measures relations between the quality and the temperature of the material under the program- controlled temperature and then research the physics and chemical change rate and involved energy and quality changes when the material is heated or cooling [2].

And then it puts forward that the volume of the lost of materials caused by erosion is equal to the void under slab and gets the prediction models of voids beneath slab corner and along longitudinal joint edge.
Then after N times' standard axle loads, the scouring loss volume of base materials is VC
(9) The loss volume of base materials in the process of erosion is equal to the added volume of void pyramid△V2, as follows

And the employed material properties such as yield strength for TGO and metal substrate at the high temperature, as well as the TGO thickness increase were hypothesized in these works due to the difficulty in obtaining the actual material parameters.
Fig.1 Geometry model and mesh representation Simulation scheme In ABAQUS software it provides three types of fracture criteria, namely, critical stress at a certain distance ahead of the crack tip, critical crack opening displacement, and crack length versus time, to simulate crack propagation occurring in real materials.
