Analysis of damping in layered welded structures using response surface methodology approach

Analysis of damping in layered welded structures using response surface methodology approach Response surface methodology with Box-Benhken (BB) design of experiment approach has been utilised to study the mechanism of interface slip damping in layered and jointed tack welded beams with varying surface roughness. The design utilises the initial amplitudes of excitation, tack length and surface roughness at the interfaces to develop the model for the logarithmic damping decrement of the layered and jointed welded structures. Statistically, designed experiments have been performed to estimate the coefficients in the mathematical model, predict the response, and check the adequacy of the model. Comparison of predicted and experimental response values outside the design conditions have shown good correspondence, implying that empirical model derived from response surface approach can be effectively used to describe the mechanism of interface slip damping in layered and jointed tack welded structures. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png International Journal of Structural Engineering Inderscience Publishers

Abstract

Response surface methodology with Box-Benhken (BB) design of experiment approach has been utilised to study the mechanism of interface slip damping in layered and jointed tack welded beams with varying surface roughness. The design utilises the initial amplitudes of excitation, tack length and surface roughness at the interfaces to develop the model for the logarithmic damping decrement of the layered and jointed welded structures. Statistically, designed experiments have been performed to estimate the coefficients in the mathematical model, predict the response, and check the adequacy of the model. Comparison of predicted and experimental response values outside the design conditions have shown good correspondence, implying that empirical model derived from response surface approach can be effectively used to describe the mechanism of interface slip damping in layered and jointed tack welded structures.
