A New Method for Predicting Extensive Ductile Tearing Using Finite Element Analysis

A new method employing the fitting of a least squares plane to stress distribution obtained from a finite element analysis for evaluating categorized values is presented. The property of a least squares fit, i.e., the preservation of volume under stress distribution and the plane of consideration, is used in evaluating various numerical integrals. The procedure is demonstrated through application to a typical shell nozzle junction.

Stress linearization is used to define constant and linear through-thickness FEA (Finite Element Analysis) stress distributions that are used in place of membrane and membrane plus bending stress distributions in pressure vessel Design by Analysis. In this paper, stress linearization procedures are reviewed with reference to the ASME Boiler & Pressure Vessel Code Section VIII Division 2 and EN13445. The basis of the linearization procedure is stated and a new method of stress linearization considering selected stress tensors for linearization is proposed.

This paper presents a new method for the analysis of the crankshaft strength by using the softwares of solidworks, matlab and ansys. Using the powerful modeling function of solidworks, the three-dimensional model of crankshaft was established. Applying the techniques of numerical operation, graph display and GUI of matlab, the simulation calculations of kinematics, dynamics of crankshaft was carried out and the force and torque of crankshaft was obtained. Making full use of finite element analysis function of ansys, the modal analysis and strength analysis of crankshaft were made. The results show that it is valid to take the respective advantages of solidworks, matlab and ansys to establish a simple and effective approach for the analysis of the crankshaft strength, which supplies foundation for the optimization design and dynamic response of crankshaft.
