Discontinuous modelling of shear bands using adaptive meshfree methods
(2008-01-15)
A simple methodology to model shear bands as strong displacement discontinuities in an adaptive meshfree method is presented. The shear band is represented by a displacement jump at discrete particle positions. The ...
Análise de aspectos fundamentais de métodos de partículas
(Universidade Estadual Paulista (Unesp), 2017-04-10)
Atualmente, devido ao grande avanço tecnológico, o uso dos métodos de partículas (Meshfree Particle Methods), vem ganhando espaço nas simulações numéricas de escoamentos. O marco inicial foi o método Smoothed Particle ...
On the numerical stability and mass-lumping schemes for explicit enriched meshfree methods
(2012-02-24)
Meshfree methods (MMs) such as the element free Galerkin (EFG)method have gained popularity because of some advantages over other numerical methods such as the finite element method (FEM). A group of problems that have ...
Estudo matemático do método SPH para modelo Wet-Dam-Break
(Universidade Estadual Paulista (Unesp), 2019-03-29)
Neste trabalho, apresenta-se o método Lagrangiano de partículas livre de malhas, Smoothed Particle Hydrodynamics (SPH). Neste método, o domínio do problema é discretizado empregando partículas que possuem propriedades ...
Particle-based fluids for viscous jet buckling
(ElsevierAmsterdam, 2015-11)
In this paper, we introduce a novel meshfree framework for animating free surface viscous liquids with
jet buckling effects, such as coiling and folding. Our method is based on Smoothed Particle Hydrodynamics
(SPH) fluids ...
Simulation of skeletal muscles in real-time with parallel computing in GPU
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2020-06-05)
The animation of humanoid characters is an ongoing research area, with a special focus within
the entertainment industry. However, the need of detailed human models has extended to areas
such as medicine, and biomechanics, ...
Aportes al modelado de la formación de la viruta en el proceso de maquinado ortogonal de materiales metálicos
(2012)
Este trabajo presenta la aproximación por el método libre de malla de Smoothed Particle Hydrodynamics (SPH) para el modelamiento de la formación de la viruta en el proceso de maquinado ortogonal de metales. Se aborda el ...
