Geometrically Nonlinear Theory of Composite Beams with Deformable Cross Sections
Aone-dimensional theory of slender structures with heterogeneous anisotropic material distribution is presented. It expands Cosserat’s description of beam kinematics by allowing deformation of the beam cross sections. For that purpose, a Ritz approximation is introduced on the cross-sectional displacement field, which defines additional elastic degrees of freedom (finite-sectionmodes) in the on...
متن کاملSimple Two Variable Refined Theory for Shear Deformable Isotropic Rectangular Beams
In this paper, a displacement-based, variationally consistent, two variable refined theory for shear deformable beams is presented. The beam is assumed to be of linearly elastic, homogeneous, isotropic material and has a uniform rectangular cross-section. In this theory, the beam axial displacement and beam transverse displacement consist of bending components and shearing components. The assum...
متن کاملInitial Postbuckling Behavior of Shear Deformable Symmetrically Laminated Beams
Abstract-Results for the initial postbuckling behavior of laminated beams are presented. Shear deformation effects are incorporated by relaxing certain assumptions of thin beam/plate theory. The analysis used is in the spirit of Koiter [Doctoral thesis, Delft, Amsterdam, English translation AFFDL-TR-70-25, (1970)], who developed asymptotic expressions for the potential energy in the neighborhoo...
متن کاملInnovative isogeometric formulations for shear deformable beams and plates
We present different innovative formulations for shear deformable beams and plates exploiting the high inter-element continuity provided by NURBS basis functions. We develop isogeometric collocation methods in standard and mixed formulations as well as Galerkin methods using an alternative set of discrete variables. All methods are free of shear locking, which is confirmed by numerical tests.
متن کاملElliptical beams.
A very general beam solution of the paraxial wave equation in elliptic cylindrical coordinates is presented. We call such a field an elliptic beam (EB). The complex amplitude of the EB is described by either the generalized Ince functions or the Whittaker-Hill functions and is characterized by four parameters that are complex in the most general situation. The propagation through complex ABCD o...
