On the Geometrically Nonlinear Analysis of Composite Axisymmetric Shells
Composite axisymmetric shells have numerous applications; many researchers have taken advantage of the general shell element or the semi-analytical formulation to analyze these structures. The present study is devoted to the nonlinear analysis of composite axisymmetric shells by using a 1D three nodded axisymmetric shell element. Both low and higher-order shear deformations are included in the ...
متن کاملGeometrically nonlinear analysis of axially functionally graded beams by using finite element method
The aim of this paper is to investigate geometrically nonlinear static analysis of axially functionally graded cantilever beam subjected to transversal non follower load. The considered problem is solved by finite element method with total Lagrangian kinematic approach. The material properties of the beam vary along the longitudinal direction according to the power law function. The finite elem...
متن کاملA New C Eight - Noded Plate Element for Static & Dynamic , Analyses of Composite Laminates
ABSTRAC~ This paper deals witU a new 48-degrees-of-freedom rectangular finite element for analysing moderately thi(:k, multilayered composite plates. The formulation is based on a kinematics which allows one to exactly ensure the continuity <londitions for the displacements, and the t~ansverse str~sses at the interfaces between the layers of a laminated structure and zero s1lress conditiQns at ...
متن کاملA geometrically nonlinear finite-element model of the cat eardrum.
Current finite-element (FE) models of the eardrum are limited to low pressures because of the assumption of linearity. Our objective is to investigate the effects of geometric nonlinearity in FE models of the cat eardrum with an approximately immobile malleus for pressures up to +/-2.2 kPa, which are within the range of pressures used in clinical tympanometry. Displacements computed with nonlin...
متن کاملDynamic Behavior Analysis of a Geometrically Nonlinear Plate Subjected to a Moving Load
In this paper, the nonlinear dynamical behavior of an isotropic rectangular plate, simply supported on all edges under influence of a moving mass and as well as an equivalent concentrated force is studied. The governing nonlinear coupled PDEs of motion are derived by energy method using Hamilton’s principle based on the large deflection theory in conjuncture with the von-Karman strain-displacem...
