Thermoelastic analysis for rotating circular HSLA steel plates with variable thickness

摘要: The solid or hollow circular HSLA steel plate is variable thickness.The center deflection decreases as the angular speed ω increases.The radial stress great affected by and temperature. Thermoelastic analysis for a rotating (high strength low alloy) with thickness, which placed in temperature field, subjected to mechanical load presented. Based on von Karman equation classical thin theory, nonlinear governing equations mid-plane displacements of are obtained using Hamilton variation principle. rotation angle discretized space time domains utilizing finite difference method Newmark method, whole problem solved iterative method. Numerical results show that geometric shape, speed, field all have influence thermoelastic behavior plate.
