According to the deep analysis of material's mechanical properties test data, the author makes a study on the strength mechanism of the concrete material.
However, due to the varieties in material production process and material shape as well as the influence of the mechanical properties and aggregate size, the strength mechanism of them is different.
The specimens material type and specimens size are shown in Table 1.

The unique characteristic of ultrasonic deburring makes it possible to be employed for the non-contact deburring of a wide range of workpiece materials.
It can be thought that when the cavitation-induced compressive stress exceeds the yield stress of material, microcracks will be formed on the surface of specimen.

Biomass is a type of organic material produced by the process of photosynthesis [1].
This alternative fuel has advantages in terms of its production process and the use of simple raw materials, indicating great potential for development.
This potential can then be developed into raw materials for producing briquettes as an alternative fuel.
