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 that, while partial delamination between the piezoelectric and non-piezoelectric layers does not affect the maximum deformation significantly, it affects the local stresses near delaminated regions.

A SHEAR FLEXIBLE FINITE-ELEMENT FOR NONUNIFORM, LAMINATED COMPOSITE BEAMS Oral, Süha (Elsevier BV, 1991-01-01) 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 geome...
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...
Development of computational software for analysis of curved girders under construction loads Topkaya, Cem (Elsevier BV, 2003-09-01) The analysis of horizontally curved, trapezoidal steel girders presents a variety of computational challenges. During the erection and construction stages before a concrete deck is available to form a closed section, these girders are weak in torsion and susceptible to warping. Considering the design of an entire bridge system, current design approaches favor the use of a grid analysis methodology. While the use of a grid analysis procedure offers the advantage of computational efficiency, it is unable to c...
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...
A new formulation for the analysis of elastic layers bonded to rigid surfaces Pinarbasi, Seval; Akyüz, Uğurhan; Mengi, Yalcin (Elsevier BV, 2006-07-01) Elastic layers bonded to rigid surfaces have widely been used in many engineering applications. It is commonly accepted that while the bonded surfaces slightly influence the shear behavior of the layer, they can cause drastic changes on its compressive and bending behavior. Most of the earlier studies on this subject have been based on assumed displacement fields with assumed stress distributions, which usually lead to "average" solutions. These assumptions have somehow hindered the comprehensive study of s...
