Comparison of two methods of fatigue testing bone cement [PDF]
, 2009 Two different methods have been used to fatigue test four bone cements. Each method has been used previously, but the results have not been compared. The ISO 527-based method tests a minimum of 10 samples over a single stress range in tension only and ...

Slurry-pressing consolidation of silicon nitride [PDF]
A baseline slurry-pressing method for a silicon nitride material is developed. The Si3N4 composition contained 5.8 wt percent SiO2 and 6.4 wt percent Y2O3. Slurry-pressing variables included volume percent solids, application of ultrasonic energy, and pH.

ELECTRON MICROSCOPIC FRACTOGRAPHY
, 1962 Electron microscopic fractography comprises the examination of replicas of fracture surfaces under the electron microscope and is a valuable tool for studying the fracture micromechanism and for analyzing service failures. The techniques of fractography are described, and the direct carbon and plastic- carbon methods of replication are compared.

Stability and roughness of tensile cracks in disordered materials
, 2013 We study the stability and roughness of propagating cracks in heterogeneous brittle two-dimensional elastic materials. We begin by deriving an equation of motion describing the dynamics of such a crack in the framework of Linear Elastic Fracture ...

Study of Fatigue Fractography of Mild Steel Used in Automotive Industry
˜Al-œKhawarizmi engineering journal, 2019 Fatigue failure is almost considered as the predominant problem affecting automotive parts under dynamic loading condition. Thus, more understanding of crack behavior during fatigue can strongly help in finding the proper mechanism to avoid the final ...

Failure Analysis of 316L Air Cooler Stainless Steel Tube in a Natural Gas Production Field
International Journal of Electrochemical Science, 2015 In spite of the excellent resistance of stainless steel (SS) towards uniform corrosion, overcoming various localized corrosion could be a real challenge. This work presents an analysis of the failure behavior of 316L SS air chiller tube with a peripheral
