Abstract: Theoretical models for the hydrodynamic lubrication of plane strain and axisymmetric sheet metal stretch forming processes with cylindrical and spherical headed punches, respectively, are developed. ...

Abstract: Force measurement and surface oil flow visualization were carried out in wind tunnel to investigate the effects of wing’s planform and flexibility on aerodynamics for flow over low-aspect ratio wings. It is found that the ...

Abstract: A model for evaluating the critical buckling capacity of long slender friction piles is developed with lateral soil support included based on the concept of the subgrade reaction. A general power distribution of the ...

Abstract: Reinforced concrete arch bridges are ideal to span over river valleys or deep ravines. However, the construction of the arch rib is very often the most crucial aspect that may influence the feasibility of the bridge. Casting ...
