Paper Abstract

The application of a full field vibration stress measurement technique is described. The application considered covers the range 30 Hz - 5 kHz on blades and other high energy components. These measurements are made to: (i) Validate a finite element model (ii) Measure the effect of local modifications (iii) Problem solve development incidents The relative successes of measuring at different frequencies are discussed. Full field stress measurements - using SPATE (Stress Pattern Analysis by Thermal Emission) have never been made in isolation from other techniques. SPATE's part in the overall vibration investigation and its relation to other measurement techniques is described.
