The 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 کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Welding Gun Inclination Detection and Curved Fillet Weld Joint Tracking
It is important to adjust the welding gun's inclination during automatic curved-joint tracking of arc welding. In this paper, a novel method is proposed to detect the deviation and inclination of the welding gun based on the arc currents acquired by a high-speed rotational arc sensor. It uses a least-squares method to fit the arc currents to a plane in three dimensions. The deviation and inclin...
متن کاملThe effect of spring restraint on weld distortion in t-joint fillet welds
T-joint fillet welds are a very common occurrence found in industry today. Localized heating and cooling from the welding process lead to the rise of distortion and residual stresses. Weld fixturing is a common practice in industry used to address the problems associated with welding, however fixturing also creates problems of residual stresses being locked into the weldment. This research invo...
متن کاملOn the strength and scope of DLS
We provide syntactic necessary and sufficient conditions on the formulae reducible by the second-order quantifier elimination algorithm DLS. It is shown that DLS is compete for all modal Sahlqvist and Inductive formulae, and that all modal formulae in a single propositional variable on which DLS succeeds are canonical.
