Impulse Excitation Modulus Measurements of Hardmetal Rods using Custom Software on a Standard Personal Computer and Microphone

A standalone piece of software was developed that records and processes the resonance spectrum produced when a rod is struck. The software uses a standard microphone and the sound card of a normal computer. This cost-effective software solution was tested against submicron hardmetal rods of circular cross-section. Transverse and longitudinal resonance modes were included. The study shows the gains that can be achieved in quality control throughput, product integrity, wastage and time. Limitations on specimen size are presented.
