Combined with the theory of heat transfer and related empirical formulas, the thermal boundary conditions for the cylinder inner wall and the outer wall has been determined, and the cylinder temperature field and thermal stress has been studied by using the finite element method in order to obtain the effect of different materials on the temperature, stress and deformation of the cylinder liner, therefore it provided theoretical basis for the design and inspection of cylinder liner.

Different materials have different characteristics and so can bring different effects on penetration course of the projectile.
For this phenomenon, it could be explained that rock materials had anisotropic and brittle characteristics which caused forming and developing of the cracks in the rock were random when the rock materials underwent impact loads, which could be furthermore proved from damage morphology of the rock layer in Fig. 4.

Such information is useful to characterize and analyze the mechanical behavior of materials.
However, near surface measurements and experiments carried out at the interface between two different materials are not easy to analyze.
High residual stresses are thus generated in both materials during the cooling of this heterogeneous transition joint.
