Numerical free vibration analysis of higher-order shear deformable beams resting on two-parameter elastic foundation
Free vibration analysis of higher-order shear deformation beam resting on one- and two-parameter elasticfoundation is studied using differential transform method (DTM) as a part of a calculation procedure. First,the governing differential equations of beam are derived in a general form considering the shear-freeboundary conditions (zero shear stress conditions at the top and bottom of a beam). ...
متن کاملDynamic Analysis of Axially Beam on Visco - Elastic Foundation with Elastic Supports under Moving Load
For dynamic analyses of railway track structures, the algorithm of solution is very important. For estimating the important problems in the railway tracks such as the effects of rail joints, rail supports, rail modeling in the nearness of bridge and other problems, the models of the axially beam model on the elastic foundation can be utilized. For studying the effects of axially beam on the ela...
متن کاملDynamic Response of Multi-cracked Beams Resting on Elastic Foundation
Cracks cause to change dynamic response of beams and make discontinuity in slope of the deflection of the beams. The dynamic analysis of the Euler-Bernoulli cracked beam on the elastic foundation subjected to the concentrated load is presented in this paper. The stiffness of the elastic foundation and elastic supports influence on vibrational characteristics of the cracked beam. The Dynamic Gre...
متن کاملNumerical Dynamic Analysis of Beams on Nonlinear Elastic Foundations under Harmonic Moving Load
As a main background practical context of the present numerical investigation, the appropriate description of track vibrations induced by high-speed trains looks crucial in contemporary railway engineering. The present paper is concerned with the modelization of the transient dynamic response of a simply-supported Euler-Bernoulli beam resting on a homogeneous in space Winkler elastic foundation...
