Boundary Layers in Weak Solutions of Hyperbolic Conservation Laws [PDF]
Archive for Rational Mechanics and Analysis, 1999 This paper is concerned with the initial-boundary value problem for a nonlinear hyperbolic system of conservation laws. We study the boundary layers that may arise in approximations of entropy discontinuous solutions. We consider both the vanishing viscosity method and finite difference schemes (Lax-Friedrichs type schemes, Godunov scheme).

A Weak Layer in the Mantle? [PDF]
Geophysical Journal International, 1937 Summary The paper discusses the effect of a weak layer in the upper mantle on the deformation of the crust arising from atmospheric loading, and on the isostatic compensation process. It also points out that S phases with periods of I second are much more strongly damped than S phases with periods of 10 seconds or more, and than P phases with short ...

Evaluating snow weak-layer failure parameters through inverse finite element modelling of shaking-platform experiments [PDF]
Natural Hazards and Earth System Sciences, 2015 Snowpack weak layers may fail due to excess stresses of various natures, caused by snowfall, skiers, explosions or strong ground motion due to earthquakes, and lead to snow avalanches.

Ultimate capacity of piles penetrating in weak soil layers
MATEC Web of Conferences, 2018 A pile foundation is one of the most popular forms of deep foundations. They are routinely employed to transfer axial structure loads through the soft soil to stronger bearing strata.

The Use of Sand Columns in the Reinforcement of Weak Layers in Road Engineering [PDF]
Archives of Civil Engineering, 2021 It is an established fact that when roads are planned and constructed, consideration needs to be given to ensuring the strength of the road surface. It is, however, also the case that when an existing road is being rebuilt or is under maintenance, its ...

Dizhi lixue xuebaoObjective As ubiquitous critical structural units in sedimentary basins, weak layers are characterized by low shear strength, low Young’s modulus, and pronounced plastic rheological behavior, playing a key role in stress accommodation and strain ...

Modeling weak snow layer fracture in propagation saw test using an ice column model
Arctic, Antarctic, and Alpine Research, 2022 Fracture initiation and propagation in a weak snow layer are two primary processes of the slab avalanche formation process. This study proposes a model for the weak snow layer and investigates the fracture propagation process.
