Abstract: This paper presents a fast treatment of essential boundary conditions in three-dimensional (3D) meshfree computation for computational efficiency. Due to the loss of Kronecker delta properties in the meshfree shape functions, ...

Abstract: The infrastructure development of emerging economies forms new market opportunities with great potential for multinational firms. However, international contractors are faced with extraordinary institutional challenges ...

Abstract: This paper focuses on the effects of particle size distribution on shear strength of accumulation soil. A series of direct shear box tests and triaxial tests were performed to characterize the shear strength of the ...

Abstract: A stabilized conforming (SC) nodal integration method is developed for elastoplastic contact analysis of metal forming processes. In this approach, strain smoothing stabilization is introduced to ...

Abstract: Surface distortions are frequently introduced into Class “A” surfaces during various sheet metal forming operations such as drawing, trimming, and flanging. The origins of these surface distortions ...

Abstract: Pile positioning, for driving piles below the surface of water in a marine pier construction project, is typically a time-consuming task owing to the fact that the pile wharf is affected significantly by environmental ...

Abstract: This paper presents the explicit mapping relations between topological structure and position and orientation characteristic (POC) of mechanism motion output. It deals with (1) the symbolic ...

Abstract: This paper studied the effects of two welding modes, i.e., keyhole penetration and full penetration, on laser welding of two zinc-coated steel stack-ups of the same total sheet thickness but different sheet thickness ...
