Comptes rendus. Mecanique, 2018 This paper is concerned with the solution to structural dynamics equations. The technique here presented is closely related to Harmonic Analysis, and therefore it is only concerned with the long-term forced response. Proper Generalized Decomposition (PGD)

The gravity dual of Lorentzian OPE blocks
Journal of High Energy Physics, 2020 We consider the operator product expansion (OPE) structure of scalar primary operators in a generic Lorentzian CFT and its dual description in a gravitational theory with one extra dimension.

Multielement Separated Representations for Orbit Uncertainty Propagation
Journal of Guidance Control and Dynamics, 2019 Uncertainty quantification is a valuable methodology in the field of astrodynamics, but approaches are often computationally expensive or rely on assumptions that do not account for non-Gaussian po...

Space–time proper generalized decompositions for the resolution of transient elastodynamic models [PDF]
, 2013 In this paper, we investigate ability of proper generalized decomposition (PGD) to solve transient elastodynamic models in space–time domain. Classical methods use time integration schemes and an incremental resolution process.

A minimally-intrusive fully 3D separated plate formulation in computational structural mechanics
Advanced Modeling and Simulation in Engineering Sciences, 2019 Most of mechanical systems and complex structures exhibit plate and shell components. Therefore, 2D simulation, based on plate and shell theory, appears as an appealing choice in structural analysis as it allows reducing the computational complexity ...

Separable Algorithmic Representations of Classical Systems and Their Applications
Contemporary Mathematics. Fundamental Directions, 2021 The main results of the theory of separable algorithmic representations of classical algebraic systems are presented. The most important classes of such systems and their representations in the lower classes of the arithmetic hierarchy - positive and negative - are described.

On the coupling of local 3D solutions and global 2D shell theory in structural mechanics
Advanced Modeling and Simulation in Engineering Sciences, 2019 Most of mechanical systems and complex structures exhibit plate and shell components. Therefore, 2D simulation, based on plate and shell theory, appears as an appealing choice in structural analysis as it allows reducing the computational complexity ...

Proper generalized decomposition of time-multiscale models [PDF]
, 2011 Models encountered in computational mechanics could involve many time scales. When these time scales cannot be separated, one must solve the evolution model in the entire time interval by using the finest time step that the model implies.
