Paper Abstract

The paper aims to illustrate the relevant use of infrared thermography as a nondestructive, noncontact and real time technique (1) to observe the progressive damage processes and mechanisms of wood failure, and (2) to detect the occurrence of intrinsic dissipation localization. The parameter investigated in this paper is the heat generation due to intrinsic dissipation caused by anelasticity and/or inelasticity of wood material. Thanks to the thermomechanical coupling, this useful technique offers the possibility of scanning mechanical phenomena of wood degradation before reaching the ultimate strength. It allows a measure of the limit of a progressive damaging process under loading beyond which the wood material is destroyed.
