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.

From Lagrange to Bernstein: Generalized Transfinite Elements with Arbitrary Nodes
MathematicsThis 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

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 ...

Can lift be generated in a steady inviscid flow?
Advances in Aerodynamics, 2023 This paper presents a critical evaluation of the physical aspects of lift generation to prove that no lift can be generated in a steady inviscid flow. Hence, the answer to the recurring question in the paper title is negative.

A Lagrange-based generalised formulation for the equations of motion of simple walking models [PDF]
Journal of Biomechanics, 2017 Simple 2D models of walking often approximate the human body to multi-link dynamic systems, where body segments are represented by rigid links connected by frictionless hinge joints. Performing forward dynamics on the equations of motion (EOM) of these systems can be used to simulate their movement.

Including connecting elements into the Lagrange multiplier state-space substructuring formulation
Journal of Sound and Vibration, 2023 This paper extends the inverse substructuring (IS) approach into the state-space domain and presents a novel state-space substructuring (SSS) technique that embeds the dynamics of connecting elements (CEs) in the Lagrange Multiplier State-Space Substructuring (LM-SSS) formulation via compatibility relaxation. This coupling approach makes it possible to
