Abstract

The finite-element method is used to carry out parametric analyses on the thermal response of simulated defects in fiber-reinforced polymer (FRP) laminates applied to a concrete substrate. The aim is to assess the potential for quantitative infrared thermography in not only detecting a flaw but also being able to describe its physical characteristics. Three parametric studies are presented, namely: 1) Relationship between the thermal input, the maximum signal, and the maximum surface temperature; 2) Effects of flaw depth and the number of FRP layers; and 3) Effect of flaw width. From these simulations, procedures are established for selecting the thermal input and estimating the flaw depth and width.
