Mechanical properties of flax fiber-reinforced composites at different relative humidities: Experimental, geometric, and displacement potential function approaches
(John Wiley & Sons Inc, 2020-08)
Due to the good mechanical properties, flax fiber-reinforced epoxy composites are being widely used as a green alternative to glass fiber composites. However, plant fibers absorb moisture from the environment, being in a ...
Análise da relação entre tensões e variações geométricas em engrenagens cilíndricas de dentes retos utilizando método analítico e numérico
(Universidade Tecnológica Federal do ParanáCuritibaBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2015-02-04)
New materials have been used on the manufacturing of spur gears with the objective of reduce the pitting. The results achieved were satisfactory to this failure mode. However, to the other failure mode knew as bending, the ...
Mechanical behaviors of carbon fiber composite sandwich columns with three dimensional honeycomb cores under in-plane compression
(Elsevier, 2013-12-31)
Mechanical properties and failure modes of carbon fiber composite egg and pyramidal honeycombs cores under in plane compression were studied in the present paper. An interlocking method was developed for both kinds of ...
Use of a Simple Mechanical Analogy to Analytically Tune the PD Controller of a Flexible Manipulator System
(2018-01-01)
A study is presented in this paper that uses a simple mechanical analogy to analytically tune the PD (proportional-derivative) controller of a linear flexible manipulator system. More specifically, the aim is to give simple ...
Teoria de funções elípticas e aplicações em soluções de sistemas periódicos em mecânica
(Universidade Estadual Paulista (Unesp), 2018-04-24)
É bem conhecido que em Mecânica Analítica muitos problemas integráveis não tem primitivas escritas em forma de funções elementares, tais como: corpo rígido assimétrico em rotação livre; pêndulo esférico, entre outros. O ...
Supersymmetric quantum mechanics method for the Fokker-Planck equation with applications to protein folding dynamics
(Elsevier B.V., 2018-03-01)
This work developed analytical methods to explore the kinetics of the time-dependent probability distributions over thermodynamic free energy profiles of protein folding and compared the results with simulation. The ...
Theoretical models to predict the mechanical behavior of thick composite tubes
(ABM, ABC, ABPol, 2012)
This paper shows theoretical models (analytical formulations) to predict the mechanical behavior of thick composite tubes and how some parameters can influence this behavior. Thus, firstly, it was developed the analytical ...
