نویسندگان
چکیده
3D forced vibrations of two-layered plates under an influence periodic in time tangential actions were studied. An asymptotic solution the corresponding problem theory elasticity was obtained. The problem, particular, models seismic on base-foundation structures. All components stress tensor and displacement vector determined. It is shown, that among these quantities ones play leading role. Cases, when found becomes mathematically exact, indicated.

Novel Procedure to Compute a Contact Zone Magnitude of Vibrations of Two-layered Uncoupled Plates
Uncoupled multilayer plates create a complex dynamical structure, where depending on input parameters and initial and boundary conditions, various vibration types appear. In spite of undoubtable achievements in static and dynamical problems of nonlinear theory of plates, the problems of contacts exhibited by multilayer plates subject to both longitudinal and transversal time-changeable loads ar...
متن کاملDosimetric Comparison of 3D Tangential Radiotherapy of Post-Lumpectomy Breast at Two Different Energies
Introduction: Radiation therapy following breast conserving surgery is one of the most common procedures performed in any radiation oncology department. A tangential parallel-opposed pair is almost always the technique of choice for this purpose. This technique is often performed based on 3D treatment planning. The aim of this study was to compare 3D treatment planning for two different energie...
متن کاملNonlinear dynamics of rectangular plates: investigation of modal interaction in free and forced vibrations
Nonlinear vibrations of thin rectangular plates are considered, using the von Kármán equations in order to take into account the effect of geometric nonlinearities. Solutions are derived through an expansion over the linear eigenmodes of the system for both the transverse displacement and the Airy stress function, resulting in a series of coupled oscillators with cubic nonlinearities, where the...

متن کاملDynamic Instability Analysis of Transverse Vibrations of Functionally Graded Rectangular Plates under Moving Masses
In this paper, dynamic instability due to parametric and external resonances of moderately thick functionally graded rectangular plates, under successive moving masses, is examined. Plate mass per unit volume and Young’s modulus are assumed to vary continuously through the thickness of the plate and obey a power-law distribution of the volume fraction of the constituent. The considered rectangu...
