Geometrically 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 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 کاملCondensation of Large Finite-element Models for Wing Load Analysis with Geometrically-nonlinear Effects
Abstract: This paper describes a procedure to construct 1-D geometrically-nonlinear structural dynamics models from built-up 3-D linear finite-element solutions. The nonlinear 1-D model is based on an intrinsic form of the equations of motion, which uses sectional inertial velocities and stress resultants as primary degrees of freedom. It is further written in modal coordinates, which yields an...
متن کاملOn newly developed assumed stress finite element formulations for geometrically and materially nonlinear problems
In this research, newly developed assumed stress hybrid elements are presented. The elements are applicable for geometrically as well as materially nonlinear problems with or without volume constraints. Variational principles using unsymmetric stresses and rotations are adopted as the basis of the formulations. The variational principles are modified through a regularization term, to eliminate ...
متن کاملFinite element analysis of geometrically necessary dislocations in crystal plasticity
We present a finite element method for the analysis of ductile crystals whose energy depends on the density of geometrically necessary dislocations (GNDs). We specifically focus on models in which the energy of the GNDs is assumed to be proportional to the total variation of the slip strains. In particular, the GND energy is homogeneous of degree one in the slip strains. Such models indeed aris...
