In addition, strong joining of dissimilar materials is increasingly required.
There is therefore a need to identify new joining methods for new applications and materials.
As the tool feeds, large plastic deformation caused by the stirring of materials leads to material welding.
Self-pierce riveting is mainly used to join aluminium sheets between a total thickness of the upper and lower sheets of 8 mm and a thickness of the lower sheet of 0.5 mm, whereas is also applied to coated steel, copper, sandwich materials [24], plastics [25], multiple sheets and dissimilar materials.

To mitigate any disastrous effect from materials to be used for protection against biofouling, the International Maritime Organization (IMO) has banned the use of toxic substances as anti-biofouling materials [21].
The study will study the properties, effectiveness or strength, and the limitation of such materials.

The glass material has been chosen as the target solid.
Different from the IDT that must work on the piezoelectric materials, the target solid can choose any materials as required.
Principle and Method According the piezoelectric effect, when an alternating voltage exerts on the piezoelectric materials, it will cause a periodical mechanical deformation in the lattice and launch various waves.

The results were shown that structure parameters had non-linear influence on dimensionless structure tensile specific stiffness, shearing specific stiffness and bending stiffness in different direction while the honeycomb core was equivalent as solid material with modified material properties.
In mirror design, the whole structure is usually made of same material to reach the same thermal mechanical property.
