Iterative Integro-Differential Techniques Based on Green’s Function for Two-Point Boundary-Value Problems of Ordinary Differential Equations

Axioms
Several iterative integro-differential formulations for two-point, second- and third-order, nonlinear, boundary-value problems of ordinary differential equations based on Green’s functions and the method of variation of parameters are presented.

Alternative displacement frame formulations in hybrid-Trefftz Kirchhoff plate p-elements

Computer Assisted Methods in Engineering and Science, 2023
The thin plate p-elements considered in this paper are based on assumed displacement field chosen so as to a priori satisfy the governing Lagrange equation within the element.

Axiomatic formulations of modified gravity theories with nonlinear dispersion relations and Finsler–Lagrange–Hamilton geometry

European Physical Journal C: Particles and Fields, 2018
We develop an axiomatic geometric approach and provide an unconventional review of modified/nonlinear gravity theories, MGTs, with modified dispersion relations, MDRs, encoding Lorentz invariance violations, LIVs, classical and quantum random effects ...

Effect of near-fault ground motion with pulse signal on dynamic response of dam-reservoir-foundation systems

Građevinar, 2023
This paper aimed to determine the effects of a pulse signal of near-fault ground motion on the dynamic response of gravity dams, including dam-reservoir-foundation interaction, using different reservoir modelling approaches such as Westergaard, Lagrange,

Sur la formule d’inversion de Lagrange [PDF]

Annales de la Faculté des sciences de Toulouse : Mathématiques, 2007
On se propose de démontrer que la formule d’inversion de Lagrange est encore valide sur un anneau commutatif, même pour une série ayant quelques termes à coefficients nilpotents avant le terme de degré 1 (dont le coefficient est inversible). On n’use que de techniques algébriques.

From Lagrange to Bernstein: Generalized Transfinite Elements with Arbitrary Nodes

Mathematics
This paper presents a unified framework for constructing transfinite finite elements with arbitrary node distributions, using either Lagrange or Bernstein polynomial bases. Three distinct classes of elements are considered.

Forced Vibration Analysis of Composite Beams Reinforced by Carbon Nanotubes

Nanomaterials, 2021
This paper presents forced vibration analysis of a simply supported beam made of carbon nanotube-reinforced composite material subjected to a harmonic point load at the midpoint of beam. The composite beam is made of a polymeric matrix and reinforced the

Hamiltonian Formulation for Continuous Systems with Second-Order Derivatives: A Study of Podolsky Generalized Electrodynamics

Axioms
This paper presents an analysis of the Hamiltonian formulation for continuous systems with second-order derivatives derived from Dirac’s theory. This approach offers a unique perspective on the equations of motion compared to the traditional Euler ...

Riemannian Calculus of Variations Using Strongly Typed Tensor Calculus

Mathematics, 2022
In this paper, the notion of strongly typed language will be borrowed from the field of computer programming to introduce a calculational framework for linear algebra and tensor calculus for the purpose of detecting errors resulting from inherent misuse ...
