A frame invariant and path-independent geometrically exact thin walled composite beam element
(Asociación Argentina de Mecánica Computacional, 2010-11)
A geometrically exact, frame invariant and path independent beam finite element for composite thin - walled beams is presented. In the proposed formulation the virtual work equations are written as a function of generalized ...
A geometrically exact composite thin-walled beam element for flexible multibody dynamics
(Asociación Argentina de Mecánica Computacional, 2011-11-04)
A geometrically exact thin-walled composite beam finite element for multibody applications is presented. In the proposed formulation the virtual work equations are written as a function of generalized strains, which are ...
Hybrid and multi-field variational principles for geometrically exact three-dimensional beams
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
This paper addresses the development of several alternative novel hybrid/multi-field variational formulations of the geometrically exact three-dimensional elastostatic beam boundary-value problem. In the framework of the ...
A hybrid-mixed finite element formulation for the geometrically exact analysis of three-dimensional framed structures
(SPRINGER, 2011)
This paper addresses the development of a hybrid-mixed finite element formulation for the quasi-static geometrically exact analysis of three-dimensional framed structures with linear elastic behavior. The formulation is ...
An EFG method for the nonlinear analysis of plates undergoing arbitrarily large deformations
(ELSEVIER SCI LTD, 2008)
The applicability of a meshfree approximation method, namely the EFG method, on fully geometrically exact analysis of plates is investigated. Based on a unified nonlinear theory of plates, which allows for arbitrarily large ...
On the dynamics of a vibration isolator with geometrically nonlinear inerter
(2018-08-01)
The inerter is a two-terminal mechanical element that produces forces directly proportional to the relative acceleration between these terminals. The linear behaviour of this element has already been described in the ...
A large deformation small strain formulation for the mechanics of geometrically exact thin-walled composite beams
(Elsevier, 2014-11)
This work presents a new formulation of the geometrically exact thin walled composite beam theory. The formulation assumes that the beam can undergo arbitrary kinematical changes while the strains remain small, thus ...
A small strain tensor for the geometrically exact thin-walled composite beam
(Asociación Argentina de Mecánica Computacional, 2013-11)
This work presents the derivation of a small strain tensor compatible with the geometrically exact kinematics of the thin walled composite beam theory. The formulation is based on the expression of the Green strain tensor ...
An Eulerian finite element with finite rotations for thin-walled composite beams.
(Asociación Argentina de Mecánica Computacional, 2010-11)
An Eulerian beam finite element for composite thin-walled beams considering arbitrary displacements and rotations is presented. As a distinct feature, the virtual work equations are written as a function of generalized ...
On exact solutions and perturbative schemes in higher spin theory
(MDPI Multidisciplinary Digital Publishing Institute, 2018)
We review various methods for finding exact solutions of higher spin theory in four dimensions, and survey the known exact solutions of (non)minimal Vasiliev's equations. These include instanton-like and black hole-like ...
