Sensitivity Analysis for Elastic Hysteresis Damping in the Time Domain and for Other Damping Models

This research is concerned with the application of sensitivity analysis to various damping force formulas within the context of hysteretic dynamic models. The damping force formulas analyzed in this study are defined for the following models: the single-degree-of-freedom (SDOF) dynamic model, the multiple-degrees-of-freedom (MDOF) dynamic model, the viscous model, Collar’s model, Reid’s model, and the convolutional model. Through the implementation of sensitivity analysis, i.e. the Sobol method, we have identified the two most critical factors that exhibit the greatest variance among the input parameters influencing the damping force formulas for these dynamic models.
