the largest debonding load among specimens, two specimens EBROG-5×10 and EBROG-10×5, which have the same groove volume, both can be considered as the specimen with the optimal groove dimensions.  In the same groove cross-section, the specimen with greater groove width showed greater maximum load and debonding load compared to the specimen with greater groove depth. Only about the specimens EBROG-5×10 and EBROG-10×5, the debonding load of EBROG-5×10 (11.98 kN) was slightly higher than that of EBROG 10×5 (11.67 kN), which does not violate the conclusion and still, the effect of the groove width is greater than the groove depth in the bearing capacity of the bond.
