New Formulation of MNDIF Method for Eigenvalue Analysis of Plates
평판의 고정밀도 고유치 해석을 위한 새로운 MNDIF법 정식 개발
Abstract
A new formulation of the MNDIF method is introduced to extract highly accurate natural frequencies of concave plates with arbitrary shape. Originally, the MNDIF method cannot yield accurate natural frequencies for concave plates. To overcome this weak point, a new approach of dividing a concave plate into two convex domains is proposed and the validity and accuracy is shown in a verification example.
