Saint-Venant's Principle

Archive for Rational Mechanics and Analysis, 1965
The principle of the elastic equivalence of statically equivalent systems of load, or Saint-Venant's Principle, is given a precise mathematical formulation and proof. Counterexamples to traditional verbal statements of the principle are given, and the results are compared with previous mathematical work on the Saint-Venant principle.

Monolithic Framework to Simulate Fluid‐Structure Interaction Problems Using Geometric Volume‐of‐Fluid Method

International Journal for Numerical Methods in Fluids, EarlyView.
A three‐dimensional fluid‐structure interaction (FSI) framework is developed using the geometric volume‐of‐fluid (VOF) interface capturing method and applied to assess largescale turbulent FSI interactions. The monolithic FSI framework is extensively validated, and despite the discontinuities across the interface, the FSI framework delivers stable and ...

Assessing Spatial Riverbed Clogging and Its Dynamics at the Reach Scale: A Coupled Approach Combining Field Measurements and 1D Hydro‐Sedimentary Numerical Modeling

River Research and Applications, EarlyView.
ABSTRACT Assessing spatial and temporal variability of clogging in gravel‐bed rivers is challenging because field methods typically rely on labor‐intensive measurements of fine‐sediment content, porosity, or hydraulic conductivity. Clogging is also highly dynamic, driven by hydro‐sedimentary conditions; yet few studies have examined it at large scales ...

Exact boundary controllability of nodal profile for Saint-Venant system on a network with loops

Journal des Mathématiques Pures et Appliquées, 2019
The exact boundary controllability for hyperbolic systems can not be realized generally on a network with loops (see [16] ). In this paper we consider the exact boundary controllability of nodal profile on a network with loops.

Spatial Decay Estimates for Elastic Plate System With Type II Heat Conduction

Journal of Mathematics
The classical Saint-Venant principle has been extensively studied for harmonic and biharmonic models but remains largely unexplored for thermomechanical plates governed by hyperbolic (Type II) heat conduction, a conservative thermal model with unique ...

Numerical modeling of the flood routing and zoning by Saint-Venant in the river Bostanak [PDF]

پژوهش‌های زیرساخت‌های عمرانی, 2019
The equations governing transient open-channel flow are continuity and momentum equations that are known as Saint-Venant equation. Based on the simplifications of this equation, numerical models of flood routing are categorized.

Affinification: A Fine Approximation of Deformations

Computer Graphics Forum, EarlyView.
Abstract We introduce affinification, a novel method for accelerating physics‐based animation of elastic solids. During a time‐dependent simulation, our method automatically partitions the space into affine and elastic regions depending on the deformation.
