A boundary element formulation based on a direct time-domain formulation using the elastostatic fundamental solutions was used. Effects of shear deformation and rotatory inertia were included in the formulation. Shallow shell was modeled coupling boundary element formulation of shear deformable plate and two-dimensional plane stress elasticity. Domain integrals related to inertial terms were treated using the Dual Reciprocity Boundary Element Method. Several examples are presented to demonstrate the efficiency and accuracy of the proposed formulation. © 2014 Elsevier Ltd.Recurso electrónicoapplication/pdfenghttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/article10.1016/j.engstruct.2014.01.010Boundary element methodDual reciprocity boundary element methodDynamic harmonic analysisHarmonic excitationModal analysisShear deformable shallow shellsBoundary element formulationsDual reciprocity boundary element methodFundamental solutionsHarmonic excitationRotatory inertiaShallow shellsShear deformable plateTwo-dimensional planesBoundary element methodElasticityHarmonic analysisModal analysisShear deformationVibration analysisShells (structures)Boundary element methodDeformation mechanismElastoplasticityHarmonic analysisNumerical modelShear strengthStructural analysisStructural responseVibrationinfo:eu-repo/semantics/restrictedAccessAtribución-NoComercial 4.0 InternacionalUniversidad Tecnológica de BolívarRepositorio UTB24537991200
