Numerical model for the stress field ahead of a crack in elastoplastic regime
(2019-01-01)
Damage-tolerant designs admit the pre-existence of defects and small cracks, which lead to stress redistribution in structural components. The accurate knowledge of the stress field in parts under these conditions is ...
Water waves generated by local disturbance: Serre's model validity
(2002-12-01)
Water waves generated by landslides were long menace in certain localities and the study of this phenomenon were carried out at an accelerated rate in the last decades. Nevertheless, the phase of wave creation was found ...
Possibilities and limitations for the back analysis of an event in mountain areas on the coast of São Paulo State, Brazil using RAMMS numerical simulation
(2019-01-01)
Debris flows are mass movements that develop along drainage networks and involve generally dense fluids, compose of materials of different grain sizes, as well as woods and variable amounts of water, identified as natural ...
An application of the Element Free Galerkin Method to the analysis of quantum well structures
(World Publishing Corporation, 2000-01-01)
In order to obtain the quantum-mechanical properties of layered semicondutor structures (quantum well and superlattice structures, for instance), solutions of the Schrodinger equation should be obtained for arbitrary ...
Application of the PTT Model to Axisymmetric Free Surface Flows
(Amer Inst Physics, 2013-01-01)
This work is concerned with numerical simulation of axisymmetric viscoelastic free surface flows using the Phan-Thien-Tanner (PTT) constitutive equation. A finite difference technique for solving the governing equations ...
Numerical analysis of waves attenuation by vegetation in enclosed waters
(2018-01-01)
Numerical simulations using the SWAN-VEG model (Simulating WAves Nearshore, with vegetation module) were performed considering the case of Ilha Solteira (SP) reservoir, a navigable stretch of the Tiete—Paraná waterway. The ...

(Crc Press-balkema, 2018-01-01)
Numerical simulations using the SWAN-VEG model (Simulating WAves Nearshore, with vegetation module) were performed considering the case of Ilha Solteira (SP) reservoir, a navigable stretch of the Tiete-Parana waterway. The ...
Transient Numerical Model For Phase Change Thermal Storage System Analysis And Design
(ASME, United States, 1999)
A Numerical Study of the FENE-CR Model Applied to a Jet Flow Problem
(Amer Inst Physics, 2013-01-01)
The FENE-CR model is investigated through a numerical algorithm to simulate the time-dependent moving free surface flow produced by a jet impinging on a flat surface. The objective is to demonstrate that by increasing the ...
Analysis of the external region of the Pluto system for different values of inclination and eccentricity of the particles
(2017-01-01)
Pluto and Charon form a binary system due to the large mass ratio (μ = 0.12) and the small distance (d = 19570km) between them. Four small satellites, discovered after the launch of the New Horizons spacecraft, are located ...
