Análise de parâmetros relacionados à difusão de campo acústico em recintos fechados
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia MecânicaUTFPR, 2019-06-27)
Noise attenuation and control is an important attribution of engineers, because noise pollution may harm the lives of people or disturb the balance of biological systems. Handling and acoustic treatment as a way to not ...
h- and p-adaptivity driven by recovery and residual-based error estimators for PHT-splines applied to time-harmonic acoustics
(Elsevier Ltd, 2019)
© 2019 Elsevier Ltd In this work, we demonstrate the application of PHT-splines for time-harmonic acoustic problems, modeled by the Helmholtz equation. Solutions of the Helmholtz equation have two features: global oscillations ...
Scrutinizing interlaminar fatigue loading cycle in composites using acoustic emission technique: Stress ratio influence on damage formation
(2020-11-01)
Current models for delamination propagation prediction in fiber-reinforced polymer (FRP) composites exhibit limitations to explain the physics underlying the mechanisms of damage formation in fatigue. In order to contribute ...
Time domain scattering of acoustic plane waves by vertical faults
(1996)
Acoustic plane wave scattering at a vertical fault structure represents the simplest two-dimensional model of geophysical exploration that can be investigated by analytical techniques. The exact and complete solution, in ...
AcMus: an open, integrated platform for room acoustics research
(Sociedade Brasileira de Computação, 2008)
This article describes the design, implementation, and experiences with AcMus, an open and integrated software platform for room acoustics research, which comprises tools for measurement, analysis, and simulation of rooms ...
Saddle-Node Bifurcations and Design Parameters for Single-Axis Acoustic Levitators
(2020-01-01)
Acoustic levitation (Aclev) is an important tool to noncontact handling of containerless objects. In the recent years, many devices have been successfully developed due to the stable behavior of the Aclev devices. As a ...
