Effects of the Erosion and Transport of Fine Particles due to Seepage Flow
(American Society of Civil Engineers, 2003)The gradual erosion and transport of fine particles are among the possible consequences to the subsoil of a severe seepage flow, such as the seepage induced by the artificial lowering of the water table by means of pumping ... -
Discussion of “Associated and Nonassociated Aspects of the Constitutive Laws for Coupled Elastic/Plastic Materials” by I. F. Collins
(American Society of Civil Engineers, 2003) -
Coupling of FEM and DDA Methods
(American Society of Civil Engineers, 2002)Problems governed by both continuum and discontinuum like tunnels and caverns are best analyzed by the coupling distinct element method and finite element or boundary element method. This article introduces a technique in ... -
Computation of Bearing Capacity Factor Nγ—Terzaghi’s Mechanism
(American Society of Civil Engineers, 2003)A procedure based on Kötter’s equation is developed for the evaluation of bearing capacity factor -
Numerical Study of the Effect of Preloading on Undrained Bearing Capacity
(American Society of Civil Engineers, 2003)In practice the situation often arises where extra load needs to be added onto existing foundations. This can arise due to the installation of additional equipment in a building, or to the construction of new floors, etc. ... -
An Automatic Newton‐Raphson Scheme
(American Society of Civil Engineers, 2002)This article presents an automatic Newton‐Raphson method for solving nonlinear finite element equations. It automatically subincrements a series of given coarse load increments so that the local load path error in the ... -
Effect of Stress‐Dependent Base Layer on the Superposition of Flexible Pavement Solutions
(American Society of Civil Engineers, 2002)Flexible pavement structural analysis for design usage must consider (as a minimum) multiple wheel/axle loading configurations, seasonal variations of material layer properties, and the nonlinear behavior of unbound ... -
Structural Design of Flexible Pavements Using Steel Netting as Base Reinforcement
(American Society of Civil Engineers, 2002)This article deals with the structural design of flexible pavements reinforced by steel nettings. The purpose is to estimate the gain in base material obtained by using such systems. Most of the current pavement design ... -
Numerical Modeling of Air Losses in Compressed Air Tunneling
(American Society of Civil Engineers, 2002)A numerical model has been developed to predict the air losses from tunnel face and perimeter walls in compressed air tunneling. The model can also predict the zone of ground influenced by air flow from the face and walls ... -
3D Finite Element Model for Asphalt Concrete Response Simulation
(American Society of Civil Engineers, 2002)An extensive experimental, analytical, and numerical investigation on the response of asphalt concrete is currently in progress at Delft University of Technology. The objectives of this Asphalt Concrete Response (ACRe) ... -
Associated and Non‐Associated Aspects of the Constitutive Laws for Coupled Elastic/Plastic Materials
(American Society of Civil Engineers, 2002)Previous analyses are amplified to demonstrate that when the constitutive equations for geo‐materials, in which the elastic moduli depend on the plastic strain, are derived from basic thermo‐mechanical principles, the ... -
Kinematic Hardening Model for Pipeline‐Soil Interaction under Various Loading Conditions
(American Society of Civil Engineers, 2002)A kinematic hardening two‐surface model of soil‐footing interaction for pipelines under various loading conditions is presented. The model requires 13 parameters. Most of these parameters can be derived directly from a set ... -
Modeling Measured 3D Tire Contact Stresses in a Viscoelastic FE Pavement Model
(American Society of Civil Engineers, 2002)Three‐dimensional (3D) contact stresses occurring between the road surface and the tire that were measured with the South African Vehicle Road Surface Pressure Transducer Array (VRSPTA) device under a moving wheel are ... -
Rigorous Similarity Solutions for Cavity Expansion in Cohesive‐Frictional Soils
(American Society of Civil Engineers, 2002)The problem of cavity expansion from zero radius has no characteristic length and therefore possesses a similarity solution, in which the cavity pressure remains constant and the continuing deformation is geometrically ... -
On the Fundamental Solution of Dynamic Poroelastic Boundary Integral Equations in the Time Domain
(American Society of Civil Engineers, 2002)In this article, boundary integral equations (BIE) and Laplace transform domain fundamental solutions to the u‐p formulation of two‐dimensional dynamic poroelasticity are derived. Time domain fundamental solutions have ... -
