High Temperature Strain Measurements Using Digital Optics
Abstract
Current methods used to measure strain at high temperatures depend on undesireable attachments or indentations and are generally limited to temperatures below 1800 deg F. The objective of this effort is to develop, construct, and demonstrate an ultrahigh-temperature strain measurement system using unobtrusive thin material coatings applied to test samples as reference marks for optical strain monitoring. The contents of this report describe the development of a system capable of measuring strain on specimens at temperatures ranging from room temperature to above 2000 deg F.
