In this paper fracture surface of the fatigue delamination have been investigated. Fatigue delamination tests were performed on the crabon/epoxy under different stress ratios. Samples were cut from the DCB specimens and analyzed in Laser Confocal Scanning Microscope. The analysis was used to measure the roughness values. Different fractographic features observed in the study are discussed.
X-ray diffraction observation of metal fracture provides fracture analysis with useful information on the mechanics and mechanical conditions of fracturing. This method is called “X-ray Fractography” and has been developed especially in Japan as a new engineering tool for fracture analysis[1-3]. X-ray fractographic technique was applied to fracture surface of dental material. The relationship b...
OBJECTIVES To observe porcelain veneer behavior of zirconia and metal-ceramic full coverage crowns when subjected to compression testing, comparing zirconia cores to metal cores. STUDY DESIGN The porcelain fracture surfaces of 120 full coverage crowns (60 with a metal core and 60 with a zirconia core) subjected to static load (compression) testing were analyzed. Image analysis was performed u...
