Fourier nite element model for prediction of thermal buckling in disc clutches and brakes
نویسندگان
چکیده
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 problems with multiple waves along the circumference. It is shown that there exists a particular wave number with which the buckling temperature reaches a minimum. This research has potential applications in automotive clutch and brake designs against thermal buckling. ARTICLE HISTORY Received 31 December 2015 Accepted 2 March 2016

Local Imperfection Effects on Thermal Buckling Behavior of Composite Fiber Reinforced Truncated Conical Liner
Thermal buckling behavior of truncated conical liner reinforced by laminated composite is investigated in the presence of a general initial imperfection. For this purpose, the method of virtual work and first-order strain-deformation shell theory are employed to extract equilibrium equations. To this end, a finite element code is developed using the 3D 8-node shell element with six degrees of f...

متن کاملPipeline upheaval buckling in clayey backfill using numerical analysis
Offshore pipelines used for oil and gas transportation are often buried to avoid damage from fishing activities and to provide thermal insulation. Thermal expansion and contraction of the pipeline during operation can lead to lateral or upheaval buckling. A safe buried pipeline design must take into account a reliable evaluation of soil uplift resistance and pipe embedment depth. While the cost...
