Rotational invariants in finite element formulation of three-dimensional beam theories
This paper introduces a new finite element formulation of the ‘geometrically exact finite-strain beam theory’. The formulation employs the generalized virtual work principle. In the resulting governing equations of the beam, the strain vectors are the only unknown functions. The consistency condition that the equilibrium and the constitutive internal force and moment vectors are equal, is enfor...
متن کامل[hal-00855912, v1] A geometrically exact spatial beam finite element based on the fixed-pole approach
A spatial geometrically exact finite element based on the fixed-pole approach of an arbitrary order is presented. In contrast to the original formulation by Bottasso and Borri, this formulation uses standard kinematic unknowns and is therefore combinable with standard finite elements. Preliminary results show that when updating displacements and rotations at integration points, this formulation...
متن کاملUnified formulation of geometrically nonlinear refined beam theories
By using the Carrera Unified Formulation (CUF) and a total Lagrangian approach, the unified theory of beams including geometrical nonlinearities is introduced in this paper. According to CUF, kinematics of one-dimensional structures are formulated by employing an index notation and a generalized expansion of the primary variables by arbitrary cross-section functions. Namely, in this work, lowto...
متن کاملIntroducing the Logarithmic finite element method: a geometrically exact planar Bernoulli beam element
We propose a novel finite element formulation that significantly reduces the number of degrees of freedom necessary to obtain reasonably accurate approximations of the low-frequency component of the deformation in boundary-value problems. In contrast to the standard Ritz–Galerkin approach, the shape functions are defined on a Lie algebra—the logarithmic space—of the deformation function. We con...
متن کاملEffect of Abutment Angulation and Material on Stress and Strain Distributions in Premaxillary Bone: A Three-Dimensional Finite Element Analysis
Background and Aim: Dental implants with angled abutments are often inserted in the anterior maxillary region due to the status of the residual ridge and aesthetic considerations. The purpose of this study was to assess stress and strain distributions in the premaxillary bone around dental implants by means of finite element analysis (FEA). Materials and Methods: Four three-dimensional (3D) fi...
