Abstract

A method for the prediction of strain responses in a linear beam system using only output data—without direct measurement of stress or strain—is suggested. An indirect method is evaluated for predicting the strain behavior at a “hot spot” on a notched simple beam using the frequency response function (FRF) relating strain and acceleration. The dynamic response of the simple beam is obtained through uniaxial excitation. The results show that the prediction of dynamic strain is accurate within an error of less than 10% as compared to the measured strain data, indicating that the FRF prediction method is reliable enough to be used in practical applications.
