The corresponding technological measures can be adopted as the guidance for materials selection and reasonable matching in the designing.
In other words, the integrated strength facilitates shooting the material properties and thickness which can make full use of the materials and get the best formability of TWB.
The simulation results are as follows: (1) In the case of same base metals: the discrepancy of integrated strength between two base materials increases with thickness ratio.

Introduction The study of the dynamic destructive mechanism of various solid materials under a high pressure water jet lies in the center of theoretical investigation of a hydro jet.
Damage mechanics theory is able to reflect the physical process of dynamic destruction of different types of materials [1].
The reason was that isotropic materials were adopted at the model but there were some defects in the practical molding sand.
