Keywords: Induction heating Electric field Temperature field Hard-coupled formulation Higher-order finite element method a b s t r a c t A novel mathematical model of local induction heating of very thin metal plates in an external time-variable magnetic field is suggested. Distribution of eddy currents induced in the plate is modelled by electric vector(More)
A thermoelastic actuator for accurate settings of position is analyzed. Its mathematical model consisting of three partial differential equations is solved numerically in the hard-coupled formulation. The results (time evolution of the average temperature and dilatation of the working element) are compared with the data obtained by measurements on an(More)
A complete model of a cylindrical induction shrink fit between the disk and shaft is presented. The model consists of two independent parts. The first part is aimed at the purely mechanical aspects of the shrink fit (determination of the interference between both parts necessary for transferring the prescribed torque and reduced stress in both parts for the(More)
