Identification of parameters in the torsional dynamics of a drilling process through Bayesian statistics
Mario Germán Sandoval, Americo Cunha, Rubens Sampaio
This work presents the estimation of the parameters of an experimental setup, which is modeled as a system with three degrees of freedom, composed by a shaft, two rotors, and a DC…
Computational modeling of the nonlinear stochastic dynamics of horizontal drillstrings
Americo Cunha, Christian Soize, Rubens Sampaio
This work intends to analyze the nonlinear stochastic dynamics of drillstrings in horizontal configuration. For this purpose, it considers a beam theory, with effects of rotatory i…
On the nonlinear stochastic dynamics of a continuous system with discrete attached elements
Americo Cunha, Rubens Sampaio
This paper presents a theoretical study on the influence of a discrete element in the nonlinear dynamics of a continuous mechanical system subject to randomness in the model parame…
Uncertainty quantification through Monte Carlo method in a cloud computing setting
A. Cunha, R. Nasser, R. Sampaio +2
The Monte Carlo (MC) method is the most common technique used for uncertainty quantification, due to its simplicity and good statistical results. However, its computational cost is…
Sound transmission loss through double glazing windows in low frequency range
Walid Larbi, Chaima Soussi, Jean-François Deü +1
The domestic windows in the exterior building facade play a significant role in sound insulation against outdoor airborne noise. The prediction of their acoustic performances is cl…
A bifurcation and symmetry discussion of the Sommerfeld effect
Eoin Clerkin, Rubens Sampaio
The Arnold Sommerfeld effect is an intriguing resonance capture and release series of events originally demonstrated in 1902. A single event is studied using a two degree of freedo…
