Numerical Method Of Solution

The paper proposes the numerical method of solution the problems of calculation the stress state in thick-walled cylinders and spheres from physically nonlinear inhomogeneous material. The urgency of solved problem due to the change of mechanical properties of materials under the influence of different physical fields (temperature, humidity, radiation, etc.). The deformation diagram describes the three-parameter formula. The numerical method used the method of successive approximations. The results of numerical calculation are compared with the test analytical solutions obtaining the authors with some restrictions on diagram parameters. The obtained results can be considered quite satisfactory.

Gas Journal Bearing

An externally pressurized gas journal bearing with multiple supply holes is analysed theoretically by numerical method of solution. The load and flow are predicted by considering both axial and circumferential flow. These load and flow expressed in dimensionless factors are presented for different bearing design parameters. The results are compared with the similar available approximate method.
