Timoshenko versus Euler beam theory: Pitfalls of a deterministic approach
(ELSEVIER SCIENCE BV, 2011)
The selection criteria for Euler-Bernoulli or Timoshenko beam theories are generally given by means of some deterministic rule involving beam dimensions. The Euler-Bernoulli beam theory is used to model the behavior of ...
Electron beam-induced structural transformations of MoO3 and MoO32x crystalline nanostructures

Nonlinear elastic analysis of concrete beams based on the Smeared Crack Approach
(Institute of Physics Publishing, 2020-02-07)
In the present study, an analysis of plain and reinforced concrete beams under monotonic loading was made based on the Fixed Smeared Crack approach. The objectives of this research were to analyze the nonlinear behavior ...
A Novel Approach to Design and Evaluate BNCT Neutron Beams Combining Physical, Radiobiological, and Dosimetric Figures of Merit
(MDPI, 2021-02-26)
(1) Background:The quality of neutron beams for Boron Neutron Capture Therapy (BNCT) is currently defined by its physical characteristics in air. Recommendations exist to define whether a designed beam is useful for clinical ...
Dynamics of magneto electro elastic curved beams: Quantification of parametric uncertainties
(Elsevier, 2015-12-01)
The objective of this paper is the evaluation of uncertainty propagation associated to several parameters in the dynamics of magneto-electro-elastic (MEE) curved beams. These MEE structures can be employed as imbedded parts ...
Hyalella azteca used for the evaluation of cyanotoxins before and after irradiation with electron beam
(Associa????o Brasileira de Energia Nuclear, 2019)
Low-energy nuclear reactions with double-solenoid based radioactive nuclear beam
(INDIAN ACAD SCIENCES, 2010)
The University of Notre Dame, USA (Becchetti et al, Nucl. Instrum. Metho ds Res. A505, 377 (2003)) and later the University of Sao Paulo, Brazil (Lichtenthaler et al, Eur. Phys. J. A25, S-01, 733 (2005)) adopted a system ...
A matheuristic for the selection of beam directions and dose distribution in radiotherapy planning
(2015)
In this paper a matheuristic using a combined Genetic Algorithm (GA) and exact method approach is proposed for selecting the position of the beams and dose distribution in Intensity Modulated Radiotherapy Planning (IMRT). ...
Coupled Free Vibrations Of Tapered Box-Beams Made Of Composite Materials
(Asociación Argentina de Mecánica Computacional, 2006-11)
In this paper, analytical solutions are developed for the free vibration analysis of tapered thin-walled laminated-composite beams with closed cross-sections. The present approach is based in a recently developed model ...
