Abstract:

Two techniques are presented for the measurement of internal deformations in members composed of a large mass of load-bearing, viscoelastic material. In Part A, an embedded particle, X-ray scintillation detector system is described which acquires displacement data from cylindrical models less than 6-inch diameter. A brief description of the X-ray facility and its operation, specimen design and casting are presented. In Part B, a device is described that measures strain up to 50 on viscoelastic materials such as the binder used in solid-propellant motors. The transducers active element is a mercury base fluid column of 6-mil diameter and 0.5-inch length.
