Fatigue Strength of Medial Column Plates
Introduction: The use of plate systems represents a well-recognized technique for obtaining an effective compression, reduction and stabilization of the medial column of the foot. In this study, the in vitro fatigue strength of NCM (Medial Column Fusion) plates was determined and compared to a competitor’s equivalent foot system. Material: Two plates were investigated: Stryker VariAx 2 NCM Plat...
متن کاملThe Fatigue Strength of Fillet Welded Connections
This report describes a study of the fatigue behavior of fillet welded joints stressed perpendicular to the weld line. The study included an experimental phase in which the stiess-life and cracking behavior of load and nonload carrying fillet weld joints was determined. This experimental study concentrated on the fatigue behavior in the transition region between high and low cycle fatigue 3 5 (...
متن کاملStrength gradient enhances fatigue resistance of steels
Steels are heavily used in infrastructure and the transportation industry, and enhancing their fatigue resistance is a major challenge in materials engineering. In this study, by introducing a gradient microstructure into 304 austenitic steel, which is one of the most widely used types of stainless steel, we show that a strength gradient substantially enhances the fatigue life of the material. ...
متن کاملEnhancing Fatigue Strength by Ultrasonic Impact Treatment
Enhancement in fatigue performance of welded joints by Ultrasonic Impact Treatment (UIT) was evaluated in large-scale specimens having a nominal yield strength of 345 to 690 MPa. Eighteen rolled-beam specimens having welded details at cover plates and transverse stiffeners and eight built-up specimens having only transverse stiffener details were fatigue tested after treating them by UIT. A par...
متن کاملshear bond strength of orthodontic buccal tubes to porcelain
background: bonding of molar tubes is becoming more popular in orthodontics. occasionally, these bonding are done on posterior porcelain crowns or bridges. the purpose of this study was to evaluate the shear bond strength of buccal tubes on feldspathic porcelain crowns with two different methods. materials and methods: forty porcelain right molar crowns were fabricated for this study. the crown...
