  • Expanded plug method for developing circumferential mechanical properties of tubular materials
    Patent number: 7140259
    Abstract: A method for determining the circumferential properties of a tubular product, especially nuclear fuel cladding, utilizes compression of a polymeric plug within the tubular product to determine strain stress, yield stress and other properties. The process is especially useful in the determination of aging properties such as fuel rod embrittlement after long burn-down.
