Due to unique a hollow tubular structure, carbon nanotubes(CNTs) not only can provide the fast channel of the reactant and product but also can prepare the specific properties of catalytic materials, and have a good chemical stability, high mechanical strength and corrosion properties, as a support, CNTs have been attracted wide-spread attention[3].

In some cases, the stresses so generated can be large enough to exceed the fracture stress of the material leading to internal cracking or plastic deformation.
The former occurrence is more likely for brittle materials and may culminate in catastrophic failure and large bursts through the entire billet [1].
For the general case of a material whose Young's modulus (E), coefficient of thermal expansion (ω), and Poisson's ratio (ν) are a function of temperature.

Introduction Delamination cracking occurs in materials with a layered structure or in which the layered location of nonmetallic inclusions is observed as linearly ordered chains.
The reason for the occurrence of delamination cracking in steels is fracturing of the layer of brittle inclusions (Fig. 1.) during loading and loss of the material cohesion.
