A numerical and experimental study of bearing stiffness of drilled shafts socketed in heterogeneous rock
(Brasil, 2012)
The objective of this study is to evaluate the effect of spatial variability of rock elasticity on the tip resistance of drilled shafts using experimental tests, finite element analysis (FEA) and geostatistical principles. ...
Arterial Stiffness Is Not Independently Associated With Nighttime Sleep Duration In Community-Dwelling Older Adults. Results From The Atahualpa Project.

On the contact stiffness and nonlinear vibration of an elastic body with a rough surface in contact with a rigid flat surface
(Elsevier B.V., 2015-01-01)
The surface topography of engineering rough surfaces has an enormous influence on contact mechanics of the interface and further the dynamics of the contact system. In this paper, the force-deflection characteristic and ...
Strength and Stiffness Parameters of an Unsaturated Tropical Soil
(Amer Soc Civil Engineers, 2018-01-01)
The interpretation of in-situ tests for site characterization of unsaturated tropical soil sites should consider both the spatial and the seasonal variability caused by the soil suction on the strength and stiffness ...
Effect of fatigue on tropical wood species

Adaptive importance sampling based neural network framework for reliability and sensitivity prediction for variable stiffness composite laminates with hybrid uncertainties
(Elsevier, 2020)
In this work, we propose to leverage the advantages of both the Artificial Neural Network (ANN) based Second
Order Reliability Method (SORM) and Importance sampling to yield an Adaptive Importance Sampling based
ANN, ...
Fadiga em peças de madeira para uso estrutural
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Civil - PPGECivCâmpus São Carlos, 2017-12-18)
The purpose of present study was to create a theoretical model that allowed with security and reliability to obtain, values of strength and stiffness to which the structural element will be submitted throughout its useful ...
On the assumed inherent stability of semi-active control systems
(Elsevier, 2018-03)
Vibration control systems are usually classified into: passive, active and semi-active. Semi-active control systems are based on formerly passive mechanical devices, such as springs and dampers, whose characteristics are ...
