Dispersion of Tracers Along the Coast of Singapore
The primary objective of the present study is to model numerically the dispersion of a cloud of fine radioactive tracers along the east coast of Singapore. The results of a hydrodynamic...
Three-Dimensional Model of a Stratified Estuary?St. Andrew Bay System, Florida
A three-dimensional modal is applied to a northwest Florida estuary to provide the initial insights into the circulation and flushing patterns of the system. The model, developed by the...
Research and Development of Wave Pump
A new device, 'Wave Pump' is introduced here. The authors present the mechanism of the system, the analytical method for discharge rate, the hydraulic model test...
A Semi-Empirical Model for an OC-OTEC Spout Flash Evaporator
A phenomenological model for the thermal-hydraulics of a spout flash evaporator is presented in this paper. The model considers the two-phase flow behavior both in the spout and in the...
Model for Nonlinear Behavior of Bolted Joints Under Bending/Tension Loading
A mathematical model to predict the load-deformation relationship of single-bolted connections in wood structures subjected to bending/tension loading is described. The model accounts...
Iterative Global/Local Finite Element Analysis
In spite of the advances in computer technology, there is still a need for more computationally efficient methods for performing stress analysis. One approach which is receiving increasing...

Rate Effects in the Deformation of Rocks
This paper gives a brief review of creep and rate effects on the behavior of rocks, within a wide range of confining pressures and temperatures, and with a special emphasis on the physical...
A Microplane Constitutive Model for Soils
A microplane model for the inelastic behavior of soils is presented. The microscopic constitutive equations are defined independentely for a set of microplanes covering all possible orientations,...
Creep of Polycrystalline Ice
This paper discusses the extension of creep models for polycrystalline ice to include the effects of a non-monotonic loading history. Attention is focussed on cyclic loading since it is...
An Extended Mixture Approach for Modeling of Fiber Reinforced Cementitious Materials
A rate-independent, anisotropic model for Fiber Reinforced Cementitious Materials (FRCMs) is presented. A continuum damage/plasticity model for the concrete and an effective fiber model...
Thermomechanical Damage Due to Hydration in Large Concrete Dams
