Title: Calculation and Analysis of Fracture Parameters of Pressure Vessels Surface Crack with Finite Element Method
Abstract: In this paper,The finite element model suitable for fracture analysis of pressure vessels surface crack is built based on ANSYS software,which can conveniently calculate stress intensity factor and J-integral.By comparing the calculated value with theoretic approximate formula,it is proved that this method has high accuracy and can meet the requirements of engineering applications.Based on the testifying,the affection of a no-dimensional factor is analyzed,which could represent the shape and dimension of surface crack,to elastic-plastic component of J-integral and the conclusion is that crack shape factor should be another consideration condition beside stress level for application range of liner elastic fracture analysis.
