Advanced Finite Element Technology for Fracture Mechanics Analysis of Cracked Shells
균열 쉘의 파기역학해석을 위한 선진유한요소기법
Abstract
A new finite element technology based on p-version of F.E.M. is discussed with reference to its potential for application to stress intensity factor computations. In linear elastic fracture mechanics, especially cracked cylindrical shells. It is shown that the p-version nutlet is far better suited for computing the stress intensity factors than the conventional h-version models with the help of three test problems. The main advantage of this technology is that the accuracy of approximation can be established without mesh refinement or the use of special procedures.
