| Summary |
This paper presents a basic concept of a new method for measuring the tension stresses of the membrane materials, which is based on resonance phenomenon induced by the sound waves. Evaluation scheme for the added mass effect on vibration of the membrane is discussed, where two different approaches are adopted. It is shown that the proposed measurement scheme can be used for the prediction apparatus of the membrane tension stresses, where the accuracy of the measurement can be achieved by proper consideration of the added mass effect of the surrounding air. More precise scheme for evaluation of the added mass effect as well as production of the measurement device of membrane stresses are next subjects for the future work.
