Vibration Analysis of a Cracked Plate Subjected to Tension Using a Hybrid Method of FEM and BFM

摘要

Vibration characteristics of centrally cracked plates subjected to uniaxial tension are analyzed using a hybrid method of the finite element method for the purpose of eigenvalue analysis and the body force method for in-plane stress analysis associated with the eigenvalue analysis. The natural frequencies and mode shapes obtained by the analyses are compared with experimental results measured by the laser holographic interferometry.
