Introduction Concrete is one of popular construction materials in civil engineering field.
Among all kinds of smart materials, piezoelectric materials such as piezoceramics (especially PZT short for Leadzirconatetitanate) have the dual functions of sensor and actuator.
The materials, methods and devices involved in the test are same as the former one.

As material model the software implemented data for AISI 4140 steel is used while the workpiece is considered to behave pure plastically.
This might be due to thermal softening of the workpiece material and a temperature field that emerges ahead of the tool tip.
For future research it is necessary to obtain proper material data to achieve results which are in agreement with experimental results.

The mechanical response of materials or structures during the explosion process is complex.
Some optical methods can conduct full-field deformation measurement under dynamic loading, which is helpful to understand the transient response of materials or structures under blast loading.

In castings which are part of the class of gearbox housings, the multiplication pressure is required to be in the range 700-1100 bar depending on the volume of the injected material.
The injection speed graph is shown in Fig. 5 and that of the multiplication pressure of the fluid material inside the mould is represented in Fig. 6.
