EXPERIMENTAL-NUMERICAL RESISTIVITY MEASUREMENTS APPROACH FOR CHARACTERIZATION IN STRUCTURAL TIMBER

International audienceThis paper deals with an experimental and numerical approach to adapt resistivity measurements, usually developed in geophysics, for the in-situ monitoring of moisture content in structural timber. This method leads to identifying timber resistivity fields, in relation to moisture content, by crosschecking the current lines injected by electrodes connected to the reachable surfaces of the investigated timber element. More precisely, it is composed of the inversion of a numerical model of electrical current injection implemented in a finite element software, through a method to minimize the error between simulation and measurements. For starters, the direct model reproduces the physical measurement: the current injection and potential difference measurement from an electrical quadrupole. Next, the inversion algorithm reconstructs the timber resistivity field from the measured resistivity data

Digital image correlation techniques to investigate strain fields and cracking phenomena in asphalt materials

This paper is the outcome of a specific task group of the RILEM Technical Committee 241-MCD "Mechanisms of Cracking and Debonding in Asphalt and Composite Pavements". The group on "Advanced Measurement Techniques" was established in 2011 to investigate DIC applications for non-destructive and non-contact measurements of strain fields during laboratory testing. The paper illustrates different DIC/optical flow applications in measuring strain distribution during laboratory testing. Specific applications of DIC for evaluating crack initiation and crack propagation in asphalt materials are presented
