Abstract

The resonant response characteristics of a tapered beam are studied using Euler–Bernoulli beam theory. The sensitivity of the beam’s maximum stress to variations in its geometry is studied for three types of harmonic pressure loading. The implications to the response of airfoil chordwise bending modes are discussed.
