An efficient PGD solver for structural dynamics applications [PDF]
Advanced Modeling and Simulation in Engineering SciencesWe propose in this paper a Proper Generalized Decomposition (PGD) solver for reduced-order modeling of linear elastodynamic problems. It primarily focuses on enhancing the computational efficiency of a previously introduced PGD solver based on the ...

Proper Generalized Decomposition of LCM Models
, 2010 Simulation of RTM processes is usually performed in 2D. Thus, only a mesh of the middle plane is needed with the associated degrees of freedom savings with respect to fully 3D modeling. However such modeling needs the definition of an equivalent in-plane permeability representing the ignored dimension (the thickness).

A proper generalized decomposition approach for high-order problems
, 2015 In this paper two different approximations for the solution of high-order problems by proper generalized decompositions (PGD) are developed. The first one is based upon the use of collocation techniques, along with Chebyshev polynomials, while the second employs Hermite polynomials in a Galerkin framework. Both approaches having pros and cons, they are

Modeling the human knee joint using the Proper Generalized Decomposition [PDF]
MATEC Web of Conferences, 2019 Nowadays, human joints specifically movable are active research topics. The lack of effective replacements and the inefficient natural healing of these joints hinders any athlete from pursuing his career if injured in his joints.

Parametric Damage Mechanics Empowering Structural Health Monitoring of 3D Woven Composites
Sensors, 2023 This paper presents a data-driven structural health monitoring (SHM) method by the use of so-called reduced-order models relying on an offline training/online use for unidirectional fiber and matrix failure detection in a 3D woven composite plate. During

Local proper generalized decomposition [PDF]
International Journal for Numerical Methods in Engineering, 2017 SummaryOne of the main difficulties that a reduced‐order method could face is the poor separability of the solution. This problem is common to both a posteriori model order reduction (proper orthogonal decomposition, reduced basis) and a priori [proper generalized decomposition (PGD)] model order reduction.
