- Abstract
The authors, based on scrupulously analyzes of the literature, as well as on their former/previous experimental results, propose a new approach in the glue testing systems, mainly destined to the wood industry. The authors' previous experimental investigations, using both Moiré Fringe Method and Holographic Interferometry lead to some useful conclusions concerning on the test specimen's optimal shape as well as to its loading conditions. In this sense, the main goal of a common glue testing system consists of in establishing the permissible (admissible) shear strength of the glues. The most of the testing systems use test specimens and loading conditions, which produce undesired supplementary solicitations and consequently the so-called shear strength established in these conditions will be far (much less) from the real one. In order to eliminate these supplementary solicitations, such as bending, peeling (the so-called peel stress), etc., there is strongly need new type of test specimen and loading conditions, too. The author also performed meticulous numerical simulation, involving ANSYS 14.0 program, in order to put in evidence the mentioned undesired supplementary solicitations. Based on both the previous experimental results and on the numerical simulations' results, the authors propose (mainly for the wood-industry) a new test specimen and also a new approach, concerning on the testing bench. The proposed new test specimen will be analyzed involving ultramodern and high-accuracy optical systems, like Digital Image Correlation (DIC) and Electronic Speckle Pattern Interferometry (ESPI). In the forthcoming period, the authors propose performing several high-accuracy experimental investigations in order to establish as accurate as possible the magnitude of the shear strength of several widely-used glues in the wood industry.
