Applicable Contact Force Models for the Discrete Element Method: The Single Particle Perspective
(The American Society of Mechanical Engineers (ASME), 2009)Several processes in nature as well as many industrial applications involve static or dynamic granular materials. Granulates can adopt solid-, liquid-, or gaslike states and thereby reveal ... -
True Cross Sectional Area of Screw Threads With Helix and Root Radius Geometries Taken Into Consideration
(The American Society of Mechanical Engineers (ASME), 2009)When evaluating the strength of threaded fasteners under external loads, stress area is commonly used. However, in order to elucidate the mechanical behavior of bolted joints more rigorously and ... -
Trends and Cost Analysis of AWJ Operation at 600MPa Pressure
(The American Society of Mechanical Engineers (ASME), 2009)Increasing the pressure of abrasive waterjet, while fixing the jet power, increases the jet’s power density and thus the cutting speed may increase. This was observed for steel, aluminum, and ... -
Evaluation of Microstructures and Creep Damages in the HAZ of P91 Steel Weldment
(The American Society of Mechanical Engineers (ASME), 2009)The creep strength of welded joints in high Cr steels decreases due to the formation of Type IV creep damage in heat-affected zones (HAZs) during long-term use at high temperatures. This paper ... -
Multiaxial Fatigue of 16MnR Steel
