Fractography Analysis of Monolithic Epoxy with Tailored Topography
The topographical features of fractured tensile, flexural, K1C, and impact specimens of monolithic epoxy have been studied and correlated with mechanical properties and surface features of samples before fracture. The topographical features studied include waviness (Wa), roughness average (Ra), root mean square value (Rq), and maximum roughness height (Rmax or Rz). As surface notches generate t...
متن کاملMODIFICATION INFLUENCE OF MISCHMETAL ON FRACTOGRAPHY FRACTURE OF G17CrMo5-5 CAST STEEL SAMPLES AFTER THE THREE-POINT BENDING TEST
J. Kasińska, Faculty of Mechatronics and Machine Design, Kielce University of Technology, Kielce, Poland The article presents the analysis of fracture surfaces after the three-point bending test at a temperature range from + 20 °C to 80 °C. The author shows a beneficial effect of mischmetal on the cracking mechanism and on the character of fractures. It has been shown that the width of the duct...
متن کاملFractography of Polymer Composites: Current Status and Future Issues
With the increasing prevalence of polymer composites in engineering applications, invariably mechanical failures of these components are occurring. Key to addressing this is fractographic analysis; the examination of fracture surfaces to deduce information about the damage and failure of components. The fractography of isotropic materials, particularly metals, has been used as a tool for many y...
متن کاملLife Estimate of a Compressor Blade through Fractography
Failure analysis of fractured components provides some information about the causes and conditions of fracture. Fractography is an indispensable part of the failure analysis as it is usually the only means by which the failure mechanism can be established. By using fractography, some information such as component’s life, values of the stress intensity factor and the applied stress can be calcul...
متن کاملFatigue behaviour and fractography of extruded AZ80 magnesium alloys in very high cycle regime
In order to investigate the fatigue properties of extruded magnesium alloy in very high-cycle regime, rotary bending fatigue test was performed in ambient atmosphere at room temperature using the hourglass shaped specimens of AZ80 alloys extruded (Fspecimen) and treated by an artificial aging after extrusion (T5-specimen). From the experimental results, both specimens show a clear step-wise S-N...
