Discontinuous Yield and Large Deformation Analysis on Rotating Disk Based on J2 deformation theory Hu Shaowei1 1Department of Materials and Structural Engineering, Nanjing Hydraulic Research Institute, Nanjing 210024, China Keywords: rotating disk, large deformation, discontinuous yield of material, J2 deformation theory, bursting speed Abstract: Rotating discs are used widely as important structural elements in mechanical engineering.
For the purpose of instability, two specific materials were chosen for analysis.
The two materials were characterized by having the same tensile strength of 77.5 ton/in2.

The volume flow rate is about 570 m3 per hour and the solid materials in the suspension are fine sands and clay materials.
Fig.2 shows the size distribution of the solid materials in the overflow from the spiral classifiers.
Hydro cyclones can used to separate the fine clay materials from the fine sands.
Conversely, most of the -0.045 mm clay materials should move to the overflow.

Experimental process The use of raw materials in this test are: copper, Cu-10.0wt%Bi master alloy, Cu-10.0wt%Se master alloy, industrical pure zinc, Cu-10.0wt%P master alloy.
The results show that the mechanical properties decline sharply with the increase of the content of bismuth.To obtain good mechanical properties materials, the content of bismuth should be controlled below 1.5wt%, and below 1.0wt% is recommended.
