An Efficient Unified Method for Thermoelastic Analysis of Functionally Graded Rotating Disks of Variable Thickness

摘要: Thermoelastic analysis of functionally-graded nonuniform rotating disks subjected to change in temperature essentially requires solutions two-point-boundary-value problems. Spatial variations thermomechanical properties, thickness, and constitute governing differential equations with variable coefficients. Closed-form such can be obtained only for specific forms grading functions. For general the numerical methods must resorted to, complementary functions method (CFM) stands as a viable option. Infusion CFM into thermoelastic thickness is unified novel approach; it efficiently used both heat conduction problems thermal stress analysis. Complementary reduces boundary-value problem an initial-value problem, which solved accurately by one many efficient methods, Runge-Kutta method. Materi...
