Sequential Simulation of Thermal Stresses in Disc Brakes for Repeated Braking
In this paper an e cient sequential approach for simulating thermal stresses in brake discs for repeated braking is presented. First a frictional heat analysis is performed by using an Eulerian formulation of the disc. Then, by using the temperature history from the rst step of the sequence, a plasticity analysis with temperature dependent material data is performed in order to determine the co...
متن کاملAn Efficient Sequential Approach for Simulation of Thermal Stresses in Disc Brakes
In this paper an efficient approach to simulate thermal stresses due to frictional heating of disc brakes is presented. In the approach thermal and stress analysis are performed sequentially. The frictional heat analysis is based on the Eulerian method, which requires significantly low computational time as compared to the Lagrangian approach. Complete three-dimensional geometries of a disc and...
متن کاملSimulation of Thermal Stresses in a Brake Disc
In this thesis thermal stresses in a brake disc during a braking operation are simulated. The simulations are performed by using a sequential approach where the temperature history generated during a frictional heat analysis is used as an input for the stress analysis. The frictional heat analysis is based on the Eulerian method, which requires significantly lower computational time as compared...
متن کاملSteady Thermal Stresses in a Thin Rotating Disc of Finitesimal Deformation with Mechanical Load
Seth’s transition theory is applied to the problems of thickness variation parameter in a thin rotating disc by finite deformation. Neither the yield criterion nor the associated flow rule is assumed here. The results obtained here are applicable to compressible materials. If the additional condition of incompressibility is imposed, then the expression for stresses corresponds to those arising ...
متن کاملFourier nite element model for prediction of thermal buckling in disc clutches and brakes
Numerical analyses are performed on thermal buckling of annular rings using a reduced Fourier method. The stress sti ness matrix is derived from the geometric nonlinearity in the Green strains with a prede ned circumferential wave number. The method is rst validated through the commercial software Abaqus using an axisymmetric model. It is then implemented to solve more general nonaxisymmetric p...
