چکیده

Shape matching is a popular method for simulating deformable objects in real time as it is fast and stable at large time steps. Although shape matching can simulate large elastic deformation and ductile fracturing, until now, they are limited to scenarios with relatively small plastic deformation. In this work, we present a method for simulating deformable solids undergoing large plastic deformation and topological changes using shape matching within the position based dynamics (PBD) framework. This expands the versatility of PBD which was previously shown to be able to simulate rigid bodies, liquids, gases, cloth, and deformable solids with moderate plastic deformation. Our novel contributions include local particle re-sampling, cluster re-sampling and skinning of an explicitly tracked surface mesh.

Simulation of the Visco-Elasto-Plastic Deformation Behaviour of Short Glass Fibre Reinforced Polyphthalamides

The importance of fibre reinforced plastics continually increases due to the excellent mechanical properties, low material and manufacturing costs combined with significant weight reduction. Today, components are usually designed and calculated numerically by using finite element methods (FEM) to avoid expensive laboratory tests. These programs are based on material models including material sp...

Failure mechanism and soil deformation pattern of soil beneath interfering square footings

In this research, the variation of ultimate bearing capacity, failure mechanism and deformation pattern of soil beneath two closely square footings have been studied using numerical methods. It is assumed that the adjacent footings are constructed on the surface of sand. The presented numerical analyses are based on explicit-finite-difference code, FLAC3D. The elasto-plastic behavior of soil is...

Direct in situ observation of metallic glass deformation by real-time nano-scale indentation

A common understanding of plastic deformation of metallic glasses (MGs) at room temperature is that such deformation occurs via the formation of runaway shear bands that usually lead to catastrophic failure of MGs. Here we demonstrate that inhomogeneous plastic flow at nanoscale can evolve in a well-controlled manner without further developing of shear bands. It is suggested that the sample und...

A finite element analysis and remeshing algorithm for an axisymmetric elasto-plastic contact problem related to indentation measurements

Non-linear quasi-static axisymmetric indentation problem is studied for comparitive computational analysis between elasto-plastic parameters and mechanical behaviour of homogeneous engineering metal materials. Mathematical model, based on deformation theory version of J2 theory, leads to quasi-static elasto-plastic contact problem with unknown contact domain, depending on the value of a indenta...
