Introduction Functionally graded materials are required for parts that operate under differentiated stress on a certain direction.
The purpose of producing such materials is to combine in same part a set of properties that cannot be obtained simultaneously.

The outcome of this study reveals the potential of SMA materials in active vibration control.
One of the popular examples of smart materials is a shape memory alloy (SMA).
Nowadays, embedding SMAs into composite materials have attracted attention from researchers around the globe.
SMA-based composites have the ability to change material properties by inducing large internal forces in the materials and modify the structure's stress and strain.

Introduction About the research on building materials by explosion, we studied explosive lining from three aspects of theoretical analysis, experimental investigation and numerical simulation from 1997.
The problems for expansion lining surrounded with two kinds of materials for the round shaft and the spherical cavity are analytically solved for the first time by elastic-plastic mechanics[4].
Applying DYNA-2D to simulate the physical process of explosive lining, we gain the varying regularity of the stress and the displacement of the building materials and the soil with time[6-7].
In the explosive lining tests, the explosion impacted on building materials was carried out in an enclosed area.
