Application of Digital Image Correlation to Structures in Fire

Published

Author(s)

Christopher M. Smith, Matthew Hoehler

Abstract

The behavior of engineering structures in fire is commonly studied through large-scale experiments. However, temperature-varying material properties, spatially-varying thermal loading and complicated structure geometries result in these structures deforming in complex and often unpredictable ways. This makes it difficult to fully characterize the response of the structure with traditional (point) sensors [1]. Full-field, noncontact measurement techniques such as Digital Image Correlation (DIC) are potentially ideal for such experiments; however, the presence of light emitted by the flames, thermal radiation from the heated structure, and convective thermal gradients in the air make this a challenging application for DIC.
