Influence of Surface Area and Geometry of Specimens on Bond Strength in a Microtensile Test: An Analysis by the Three-Dimensional Finite Element Method

“…Since 1991, researchers have described the need for a standardization of bond tests, but different methodologies have made it difficult to compare laboratory results. 25 Therefore, the data obtained in the present study must be analyzed in conjunction with the results of studies that have evaluated the bond strength of specimens submitted to microtensile tests. Concerning square sections, researchers must determine whether the cutting process damages the experimental model, which may alter the measured bond strength values.…”
