摘要: Abstract : A simple method is presented to measure the complex modulus of suitably rigid linear viscoelastic materials over audiofrequency spectrum. The case considered where one end a rod material driven harmonically and displacement ratio measured. effect mass on free accounted for. It shown that, at specific frequencies near resonance, it easy obtain data with standard equipment usually found in vibration laboratory. An experimental program described.
