An evaluation of the four-point flexural test for metal-ceramic bond strength.
An experimental and analytical stress analysis of the four-point flexural test for metal-ceramic bond strength is presented. Specimen geometry dictates whether failure occurs at the porcelain surface or at the interface under a line of force magnification. Finite element stress analysis indicates that bond separation, if it occurs, is probably due to normal tensile stresses.
