Active infrared (IR) thermographic testing procedures by 3-D finite element analysis and experimental correlations.

摘要

Infrared (IR) thermography is an emerging technology for the non-destructive evaluation (NDE) of concrete structures.; In order to develop the standard methodology of reliable IR thermographic testing procedures for NDE of concrete, analytical, numerical, and experimental studies are required. This research focuses on development of correlations of numerical and experimental studies to establish the theoretical bases for the development of a standard method of using IR thermography for non-destructive assessment of concrete.; The objectives of the study are: (1) Development of numerical heat transfer models for testing of Active IR thermographic laboratory experiments; (2) Determination of variability of surface thermal responses on void detection of concrete using IR thermography by correlating the numerical and experimental results.
