Figure 1: (a) Polyvinyl chloride pipe centralized in relation to the bracket. (b) Self-sticking adhesive on the specimen surface. (c) Metallic support with Teflon mold adapted. Note the central hole, which has dimensions equal to those of the self-sticking adhesive in the specimen. (d) Specimen undergoing the shear test. Note the semicircle-shaped active tip adapted to the specimen to exert continued strength aimed to break down the specimen
