Extreme Temperature Strain Measurement System

Abstract

A survey and a selection of optimum techniques was made of methods for making strain measurements on aerospace structures -320 deg F to 1600 deg F. Experimental evaluations were made of the two best systems selected, a rod type extensometer and a capacitance device. The rod type extensometer proved experimentally to be the better approach, especially for accurately measuring the strain behavior of an aerospace material under load throughout typical ascent and atmospheric reentry cycles. Some efforts were also devoted to the development of sputtered strain gages on transferable metal foils. These results indicated that strain measuring devices of this type could be developed if appropriate funds for research were available. Keywords: Strain measurement, Extensometer, Strain gages, Structural testing, Reentry.
