Analytical treatment of in-plane parametrically excited undamped vibrations of simply supported parabolic arches
(2003)The present work offers a simple and efficient analytical treatment of the in-plane un-damped vibrations of simply supported parabolic arches under parametric excitation. After thoroughly dealing with the free vibration ... -
Dipolar gradient elasticity of cables
(2012)The increasing structural use of cables and cable-systems has given rise to a substantial technical literature concerning their static and dynamic response. However, the majority of these works is based on classical ... -
Dosimetric and radiobiological evaluation of dose distribution perturbation due to head heterogeneities for Linac and Gamma Knife stereotactic radiotherapy
(2008)Introduction. In SRT/SRS, dedicated treatment planning systems are used for the calculation of the dose distribution. The majority of these systems utilize the standard TMR/OAR formalism for dose calculation as well as ... -
Geometrical pre-planning for conformal radiotherapy
(2007)The optimum selection of beams and arcs in conformal techniques is of the outmost importance in modern radiotherapy. In this work we give a description of an analytic method to aid optimum selection, which is based on ... -
A numerical model based on nonconvex-nonsmooth optimization for the simulation of bending tests on composite slabs with profiled steel sheeting
(2010)It is well known that the Calculation Of the ultimate strength of composite concrete slabs with profiled steel sheeting requires the determination of the longitudinal shear resistance which depends on the quality of the ... -
Size effects on strength, toughness and fatigue crack growth of gradient elastic solids
(2008)The present study investigates the microstructural size effect on the strength of a bar under axial loading, and on the toughness and crack growth of a beam under three-point bending within the framework of strain gradient ... -
Structural analysis of gradient elastic components
(2007)The present study investigates the size effects in the problems of cantilever beam bending and cracked bar tension within the gradient elasticity framework. Analytical solutions for metrics that characterize both the ...
