Abstract: This study utilizes a face-centered central composite response surface design of experiments to determine the effects of thread pitch when friction stir welding high-density polyethylene. The tool pin thread pitch, along ...

Abstract: The bistable snapthrough behavior of a compressed beam is modeled and measured experimentally as its supporting surface is bent through positive and negative curvatures. When the supporting angle of the beam exceeds a ...

Abstract: AbstractPolymeric pipes are favorable over other materials in many applications due to their ease of handling and resistance to corrosion. PVC is the most reliable piping material to resist ruptures in water drainage ...

Abstract: A nonreactive Lagrangian atmospheric diffusion model is used for the simulation of SO2 concentration around the As Pontes 1400-MW power plant located in northwestern Spain. This diffusion model has two kinds of input: 1) ...
