Abstract: A numerical-analytical method for estimating steady-state periodic behavior of nonlinear rotordynamic systems is presented. Based on a finite element formulation in the time domain, this method ...

Abstract: A method is proposed for analyzing the periodic stick-slip motion of a single degree of freedom model of frictionally damped turbine blades. The method of finite elements in the time domain ...

Abstract: This technical note develops a design approach that integrates economic design optimization with reliability-based methodologies to rationally account for geotechnical-related uncertainties. The geotechnical related ...

Abstract: A model is developed for analyzing mechanical systems with a pair of bodies with topological changes in their kinematic constraints. It is built upon the concept of a Poincaré map rather ...

Abstract: We apply the discrete time model of a mechanical system with time-varying topologies to determine its regions of stability. The backward mapping method is applied and the associated numerical ...

Abstract: The delineation of vertical geological cross-sections is an essential task in geotechnical site characterization and has a profound impact on subsequent geotechnical designs and analyses. It is a long-lasting challenge, ...

Abstract: A main challenge for risk assessment on geotechnical systems is the computational effort required when stochastic sampling methods are used. Because the deterministic models used for geotechnical systems are often complicated ...

Abstract: One of the major risks to civil structures during an earthquake is the occurrence of liquefaction in loose saturated sand deposits. The main consequences of liquefaction include lateral spreading deformations and postliqufaction ...

Abstract: Spatially varying properties of geomaterials (e.g., soils and rocks) are often measured sparsely, and the measurements inevitably contain noises or error. Therefore, interpolation of sparse geotechnical measurements ...
