This dissertation combines the dual domain material point method (DDMP) with molecular dynamics (MD) in an attempt to create a multi-scale numerical method to simulate materials undergoing large deformations with high strain rates. In these types of problems, the material is often in a thermodynamically non-equilibrium state, and conventional constitutive relations are often not available. In this method, the closure quantities, such as stress, at each material point are calculated from a MD simulation of a group of atoms surrounding

The material point method (MPM) is an evolution of the particle in cell method where Lagrangian particles or material points are used to discretize the volume of a material. The particles carry properties such as mass, velocity, stress, and strain and move through a Eulerian or spatial mesh. The momentum equation is solved on the Eulerian mesh. Modifications to the material point method are developed that allow the simulation of thin membranes, compressible fluids, and their dynamic interactions. A single

A nonlocal model for dense granular flow is implemented in the material point method (MPM), an extension of the finite element method (FEM) for solid mechanics. The nonlocal model used has shown great predictive capability for dense flows when implemented in the finite element framework, but limitations of FEM prevent application of the model to truly large scale, inhomogeneous deformations. We show that these FEM results may be replicated in the MPM framework through the solution of a vertical chute

Simulating fluids and solid materials undergoing large deformation remains an important and challenging problem in Computer Graphics. The dynamics of these materials usually involve dramatic topological changes and therefore require sophisticated numerical approaches to achieve sufficient accuracy and visual realism. This dissertation focuses on the Material Point Method (MPM) for simulating solids and fluids for use in computer animation, and it makes four major contributions: First, we introduce new MPM for simulating viscoelastic fluids, foams and sponges. Our second contribution

Correctly simulating the physics of solids and fluids is of great interest in computer graphics. A very popular method used is the Finite Element Method (FEM), however, the FEM is troublesome for large deformations or fracturing since the object needs to be remeshed periodically. Another popular option for simulation solids and fluids is to use purely particle methods such as Smoothed Particle Hydrodynamics (SPH), but the lack of connectivity between the particles presents a difficulty for calculating derivatives. Particle-In-Cell (PIC)

The primary objective of this thesis is to investigate the particle and pressure distribution of granular transitional flows using the Material Point Method (MPM). Additionally, the role of the fluid phase in submerged flows will be examined in the granular column collapse problem. Simulations of dry granular column collapse are carried out and compared to existing experimental and simulation references on the basis of runout distance and total collapse time. Model and material parameters are calibrated to match 2D plane-strain

With a focus and concentration on the simulations of real-world phenomena and materials, physics-based animation has been established as an important research area in computer graphics. However, the focus has been slightly shifted from methods for simulating new phenomena to methods for simulating existing phenomena with higher-resolution and higher-efficiency. This thesis focuses on Sparse Paged Grid (SPGrid), a sparse data structure which leverages modern operating system and hardware for compact storage and efficient stream processing, as well as its applications

The theory and algorithm for the Material Point Method (MPM) are documented, with a detailed discussion on the treatments of boundary conditions and shock wave problems. A step-by-step solution scheme is written based on direct inspection of the two-dimensional MPM code currently used at the University of Missouri-Columbia (which is, in turn, a legacy of the University of New Mexico code). To test the completeness of the solution scheme and to demonstrate certain features of the MPM, a one-dimensional MPM

The Material Point Method (MPM) has shown its high potential for physics-based simulation in the area of computer graphics. In this dissertation, we introduce a couple of improvements to the traditional MPM for different applications and demonstrate the advantages of our methods over the previous methods. First, we present a generalized transfer scheme for the hybrid Eulerian/Lagrangian method: the Polynomial Particle-In-Cell Method (PolyPIC). PolyPIC improves kinetic energy conservation during transfers, which leads to better vorticity resolution in fluid simulations
