The purpose of this paper is to demonstrate that the burst pressure of a cylindrical shell subjected to internal pressure can be accurately predicted by using finite element method. The computer software ANSYS (Swanson Analysis System Inc., 2003, “Engineering Analysis Systems User's Manual”) is employed to perform a static, nonlinear analysis (both geometry of deformation and material behavior) using three-dimensional 20 node structural solid elements. The “Newton–Raphson method” and the “arclength method” are both employed to solve the nonlinear equations. A comparison with various empirical equations shows that the static finite element method simulation using the arclength method can be employed with sufficient accuracy to predict the burst pressure of a cylindrical shell. It is also shown that the Barlow equation is a good predictor of burst pressure of cylindrical shells.

The purpose of this paper is to determine whether the finite element method can be employed to accurately predict the burst pressure of a specific cylindrical shell subjected to internal pressure. Both static and dynamic analyses were carried out. The computer code ANSYS is employed to perform a static, nonlinear analysis (both geometry of deformation and material behavior) using three-dimensional 20 node structural solid elements. The “Newton-Raphson Method” (N-R method) and the “Arc-Length Method”, are both employed to solve the nonlinear equations. The finite element code LS-DYNA is used to generate a three-dimensional finite element model by use of eight-node brick elements for the dynamic analysis. Both explicit and implicit methods are used to simulate the dynamic response of cylinders. A comparison with various empirical equations shows that both static and dynamic finite element method simulations can be employed with sufficient accuracy to predict the burst pressure of a specific cylindrical shell.

Shrink fit is an important method used to connect mechanical parts but less studied by three-dimensional finite element method. Based on the theories of induction heating and thermal conductivity, we established a three-dimensional FEM. The model included the induction coil, crank throw and air. The pattern of temperature field distribution during the period of induction heating were numerically simulated with software ANSYS .The simulation showed that, crank throw can obtain a uniform temperature field around the hole after induction heating .As a result, the crankshaft reaches a highquality shrinkage fitting, manifesting the feasibility of the application of induction heating to the crankshaft shrinkage fitting.

Abstract The paper describes the intention of the authors to determine whether it is possible to predict relative belt edge endurance for radial passenger car tires using the finite element method. Three groups of tires with different belt edge configurations were tested on a fleet test in an attempt to validate predictions from the finite element results. A two-dimensional, axisymmetric finite element analysis was first used to determine if the results from such an analysis, with emphasis on the shear deformations between the belts, could be used to predict a relative ranking for belt edge endurance. It is shown that such an analysis can lead to erroneous conclusions. A three-dimensional analysis in which tires are modeled under free rotation and static vertical loading was performed next. This approach resulted in an improvement in the quality of the correlations. The differences in the predicted values of various stress analysis parameters for the three belt edge configurations are studied and their implication on predicting belt edge endurance is discussed.
