The connection process of dissimilar materials such as aluminum and copper uses the brazing method to form a permanent joint [3].
Using the above- equation relationships, the lap length (X) was estimated for different tensile strength of the base materials.Table 1 showed the mechanical properties of materials.
At the same time, the filler materials can not quickly fill the pre-welding gap, leading to the filler materials lack of penetration, appearing large area of the bonding interface.
(3) The shear strength of the joints was influenced both by the lab length and the interactions between the filler material and base materials at the bonded interfaces

Lead zirconate titanate (PZT) is one of the most widely used ferroelectric and piezoelectric materials.
What’s more, the increasing area of deformation caused the expanding of area with different property of materials, which lead the increase of time delay.

It is shown that the DC characteristics are different with impact velocities, t/d and bumper materials[10,11].
The bumper materials are Kevlar, magnesium, aluminum 2024, titanium, molybdenum, lead and tungsten.
The projectile and bumper materials were modeled with the SPH technique.
The projectile and bumper materials are discretized as a set of particles with size of 0.05mm.
The DC characteristics vary with impact velocities, t/d and bumper materials.
