Introduction WC-Co cemented carbides are materials of choice for tools and structural components by virtue of their unique combination of hardness, strength and wear resistance.
Very little prior work has addressed the microstructure of these materials [4].
Considering the microstructure of these materials will have very important impact on the final products, especially the microstructure of the substrate after the shaping process, the microstructure of these materials should be analyzed.
It also has been found that stress concentration and residual stress will be higher at the interface and can substantially reduce the load required to fracture materials [8].

The process of filling materials is related to studies of soil and medium mechanics.
The filling performance for different materials of the bucket after optimization For the mechanical excavator, the flow patterns inside the bucket of the different materials are different.
A DEM simulation model of bucket digging materials is established, and the mining process of the bucket for different materials is simulated and analyzed.
This study not only visualizes the process of digging materials but also provides a feasible way to design the bucket structure for different materials.

The application of the finite element in analyzing the bubble in the ship wake ZHANG Qun ,WANG Yingmin School of Marine Science and Technology, Northwestern Polytechnical University, Xi’an China School of Marine Science and Technology, Northwestern Polytechnical University, Xi’an China beautyzqc@163.com, ywang@nwpu.edu.cn Keywords: finite element method, bubble in the ship wake, point displacement, pressure distribution Abstract: The finite element method was used to analyze the bubble in the ship wake.
The single bubble model in the ship wake was created and studied after the material property parameters of the bubble were got by the finite element computation.
Three different radiuses of bubbles in the ship wake were analyzed, and the parameters of the bubble materials were gained by ANSYS as the table-1 shows.
