Abstract: The structure of incylinder flow field makes significant impacts on the processes of fuel injection, air–fuel interactions, and flame development in internal combustion engines. In this study, the implementation of ...
Fatigue Damage of Aluminum Alloy Spot-Welded Joint Based on Defects Reconstruction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Three-dimensional (3D) reconstruction and finite element method are combined to study the damage behavior of aluminum alloy resistance spot-welded joints. Fatigue damage of spot-welded joints under different cyclic loading ...
Analysis of Elastic-Plastic Crack Initiation and Evolution at the Tip of an Unsaturated Inclined Open Crack under Ice–Gas–Ice Pressure
Publisher: American Society of Civil Engineers
Abstract: AbstractThe surfaces of mountain slopes in high-altitude and cold regions contain numerous
microdefects and macrodefects. These exposed cracks on the rock mass surface provide
favorable channels for the flow of water and ...
Fatigue Damage Study of Steel–Aluminum Friction Stir Welding Joints Based on Equivalent Damage Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An equivalent damage model was established to study the fatigue damage behavior of steel–aluminum friction stir welding (FSW) joints. Internal defects of friction stir welding joint under various cyclic loading stages were ...
