A shear flexible finite element is formulated for linearly tapered, symmetrically laminated composite beams. The element has three nodes and 18 degrees of freedom. The three-node configuration is obtained from a five-node parent element by constraining the shear angle variation to be linear. The bending in two planes, twisting and stretching are considered. The performance of the element is tested with isotropic and composite materials, constant and variable cross-sections, and straight and curved geometries. The element proves to be accurate and versatile. The compatibility with plate and shell elements as a stiffener is assured through the use of simple nodal variables of C0-type.

A layerwise approach to piezo-electric plates accounting for adhesive flexibility and delaminated regions Erturk, CL; Tekinalp, Ozan (Elsevier BV, 2005-01-01) Multilayer plates with piezoelectric layers are modeled considering the deformation of the adhesive layers. Special finite elements, that use linear Lagrange and conforming Hermite type interpolation functions, are developed. The results of the formulation are compared with the other results presented in the literature. Since flexible bonding formulation is also suitable for modeling delamination, case studies containing partially delaminated PZT patches are presented. It is shown for a cantilever plate tha...
ANTIPLANE SHEAR PROBLEM FOR LAMINATED COMPOSITES CONTAINING BROKEN STRIPS GECIT, MR; KULUNK, FI (Elsevier BV, 1992-08-03) This paper considers the fracture problem of a composite which consists of perfectly bonded parallel load-carrying laminates and buffer strips. It is assumed that both materials are isotropic and linearly elastic and also that the fatigue cracks may appear and spread in main laminates or in buffer strips or in both perpendicular to the interfaces. The external load is applied parallel to the crack surfaces and away from the crack region. The problem is solved for fully embedded cracks and for completely bro...
An elastic hollow cylinder under axial tension containing a crack and two rigid inclusions of ring shape Artem, HSA; Gecit, MR (Elsevier BV, 2002-11-01) This paper is concerned with the fracture of an axisymmetric hollow cylindrical bar containing rigid inclusions. The cylinder is under the action of uniformly distributed axial tension applied at infinity. The bar contains a ring-shaped crack at the symmetry plane whose surfaces are free of tractions and two ring-shaped rigid inclusions with negligible thickness symmetrically located on both sides of the crack. It is assumed that the material of the cylinder is linearly elastic and isotropic. The mixed boun...
MODELING OF CONTROL FORCES FOR KINEMATICAL CONSTRAINTS IN MULTIBODY SYSTEMS DYNAMICS - A NEW APPROACH IDER, SK (Elsevier BV, 1991-01-01) Conventionally kinematical constrains in multibody systems are treated similar to geometrical constraints and are modeled by constraint reaction forces which are perpendicular to constraint surfaces. However, in reality, one may want to achieve the desired kinematical conditions by control forces having different directions in relation to the constraint surfaces. In this paper the conventional equations of motion for multibody systems, subject to kinematical constraints, are generalized by introducing gener...
The theorems of structural variation for rectangular finite elements for plate flexure Saka, MP (Elsevier BV, 2005-11-01) The theorems of structural variation predict the forces and displacements throughout a structure without the need of fresh analysis when the physical properties of one or more members are altered or even its topology is changed due to removal of one or more of its elements. It has been shown that a single linear elastic analysis of a parent structure under the applied loads and a set of unit-loading cases is sufficient to determine the elastic, non-linear elastic and even elasticplastic response of number o...
