Introduction The new engineering materials with the advancement of modern methods in the field of aircraft and automotive industries had led to a rapid progress of metal matrix composites.
By the mean time the mold was preheated and chalk powder was applied in mould to avoid shrinkage of casting materials.

After carrying out a serious experiments, it’s believed thickness affect lifespan of focal materials to some extent.
So we can conclude that the thicker the focal materials get, the easier it would crack, and when the thinner the focal materials get, the easier it would bend.
When designing thickness of these materials we should depend on various conditions and select a optimal value.
From the simulation of thermal stress, we conclude that the thicker the focal materials get, the easier it would crack, and when the thinner the focal materials get, the easier it would bend.

In principle, in any structural element operating on bending, torsion occurs due to random eccentricity conditioned by asymmetry of section, heterogeneity of materials or off-center application of vertical load.
