Self-adaptation procedures in genetic algorithms applied to the optimal design of composite structures
International Journal of Mechanics and Materials in Design - Tập 5 - Trang 289-302 - 2009
Carlos Conceição António
It is recognized that the efficiency of Genetic Algorithms improves if some adaptive rules are included. In this work, adaptive properties in Genetic Algorithms applied to structural optimization are studied. The adaptive rules work by using additional information related to the behavior of state and design variables of the structural problem. At each generation, the self-adaptation of the genetic...... hiện toàn bộ
Modelling of the mechanical response of Zr–Nb and Ti–Nb alloys in a wide temperature range
International Journal of Mechanics and Materials in Design - Tập 16 - Trang 215-224 - 2019
Vladimir A. Skripnyak, Vladimir V. Skripnyak, Evgeniya G. Skripnyak, Nataliya V. Skripnyak
This article presents the results of modeling the mechanical behavior of Zr–Nb and Ti–Nb alloys in a range of strain rates from 0.001 to 1000 1/s and temperature range 297–1273 K. A modification of constitutive equations describing the mechanical response of fine-grained and coarse-grained Zr–1Nb and Ti–13Nb–13Zr alloys in a wide temperature range is proposed. It was shown that the phase transitio...... hiện toàn bộ
Identification of stiffness and damping characteristics of axial air-foil bearings
International Journal of Mechanics and Materials in Design - Tập 7 - Trang 231-243 - 2011
Vikas Arora, P. J. M. van der Hoogt, R. G. K. M. Aarts, A. de Boer
Air-foil bearings (AFBs) are self acting hydrodynamic bearings made from sheet metal foils comprised of at least two layers. The innermost “top foil” layer traps a gas pressure film that supports a load while the layer or layers underneath provide an elastic foundation. AFBs are currently used in many commercial applications, both terrestrial and in aerospace. AFBs provide a means to eliminate the...... hiện toàn bộ

The effect of the horizontal vibrations on natural heat transfer from an isothermal array of cylinders
International Journal of Mechanics and Materials in Design - Tập 7 - Trang 313-326 - 2011
H. Shokouhmand, S. M. A. Noori Rahim Abadi, A. Jafari
A numerical investigation is carried out to study an unsteady laminar natural convection heat transfer caused by an array of isothermal oscillating circular cylinders. Under oscillating conditions, flow and thermal fields are categorized into a class of moving boundary problems. In this study, the moving interfaces between the fluid and cylinders have been considered. The numerical model used in t...... hiện toàn bộ
A new approach on vibration analysis of locally nonlinear stiffness and damping system
International Journal of Mechanics and Materials in Design - Tập 3 - Trang 1-6 - 2006
Wang Yong, Huang Qibai, Zhou Minggang, Zhang Yongbo
The nonlinear force induced by spring and damping of 2-degree-of-freedom locally nonlinear vibrating system is regarded as applied force, and its mathematical model is established in this paper. Then impulse response temporal method of linear vibrating system is applied in the system, the response of locally nonlinear vibrating system is obtained by convolution integration between unit impulse res...... hiện toàn bộ
