CONSIDERATIONS ON THE ADHESIVE TESTING
The authors of the contribution analyse several types of the specimens, involved in the adhesives’ testing protocol. Based on the results of the Finite Element analysis, respectively of the experimental investigations ones, by means of Holographic Interferometry, they suggest a new type of specimen, which assures a more accurate evaluation of the pure shear effect in the adhesive layer. Also, their original testing stand destined to Holographic Interferometry investigations, described in an earlier contribution, can be efficiently involved in this new type of investigation of the adhesives.
The most critical issue consists of the high-accuracy determining of the shear strength of the adhesive layer, without the bending’s additional effect.
The proposed methodology and type of the specimen offer the adequate answer. The author’s further goal consists in involving this new approach in different kind of adhesives’ examination.
