... and environment that caused the fracture by a three-dimensional interpretation of the appearance of a broken component. If the specimen is well preserved and if the analyst is knowledgeable, the fracture appearance reveals details of the loading events that culminated in fracture. Fractographic analysis often...

... available for reconstructing the fracture event in microscopic detail. In this technique, the three-dimensional topographies of the conjugate fracture surfaces are simultaneously analyzed to obtain quantitative information on fracture toughness, crack nucleation times, and crack growth rates without...

To prevent infiltration of water, all three standard test methods require that the pores of the part be filled with oil. Oil impregnation is done after the part is weighed in air. This is carried out under vacuum...
