Saint-Venant's Principle

open access: yesArchive 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.

Mechanism of “seesaw‐type” rock burst in coal seam mining beneath mountainous areas

open access: yesDeep Underground Science and Engineering, EarlyView.
This study reveals the mechanism of “seesaw‐type” rock bursts during coal mining beneath mountainous areas. The advancing working face induces nonuniform fracturing of the overburden. The detached mountain mass then undergoes a seesaw‐type rotational movement around a shifting pivot, driving the primary fracture through a characteristic “open‐close ...

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

open access: yesJournal 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]

open access: yesپژوهش‌های 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.

Unlocking Hydrokinetic Energy in the Brazilian Amazon: A Statistical Resource Assessment and Economic Feasibility Analysis

open access: yesEnergy Science &Engineering, EarlyView.
This study develops a spatial and technical framework to evaluate hydrokinetic energy potential in the Amazon as a sustainable alternative to diesel‐based systems. By modeling regional resources, we demonstrate that hydrokinetic sources offer a cleaner, economically competitive solution for displacing fossil fuels in remote riverine communities ...

A multi-model approach to Saint-Venant equations: A stability study by LMIs

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2012
This paper deals with the stability study of the nonlinear Saint-Venant Partial Differential Equation (PDE). The proposed approach is based on the multi-model concept which takes into account some Linear Time Invariant (LTI) models defined around a set ...

River Ice Processes Modelling: A Comprehensive Review

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT River ice strongly influences hydrology, hydrodynamics, and ecosystems in cold regions, with an impact on flooding, hydropower generation, navigation, and aquatic habitats. Modeling river ice processes is therefore essential for both scientific understanding and operational management.

Coupling Green-Ampt and Saint-Venant Equations for Estimating of Transmission Losses during Flood Routing in Rivers [PDF]

open access: yesعلوم و مهندسی آبیاری, 2016
Volume of flooding flow volume in ephemeral streams decreases due to evaporation as well as the channel wall and bed penetration. This process is known as transmission losses.

Analysis of flood events in the Three Gorges Reservoir Region using the coupled VIC‐CaMaFlood hydrological model

open access: yesRiver, EarlyView.
Abstract In recent years, the Three Gorges Reservoir Region (TGRR) has been increasingly affected by climate change, with frequent flood events posing challenges to regional flood control. The NO.1 flood of the Daning River in 2024 further highlights the severity of flood risks in the region.

Estimation of the Torsional Rigidity of Orthotropic Solid Cross Section

open access: yesEngineering Transactions, 2021
In this paper, two inequality relations are proven for the torsional rigidity of orthotropic elastic solid cross sections. By using the derived inequality relations, lower and upper bounds can be obtained for the torsional rigidity.
