Interactive Simulation of Physically-Based Deformation, Plasticity, and Fracture
نویسنده
چکیده
We consider the problem of real-time interactive simulation of deformation, plasticity and fracture. This document compares, contrasts, and synthesizes two recent directions in the field (covered in four papers). Both directions improve upon a linear elastic model for simulating deformations and use the finite element method (FEM), but approach the problem of handling large rotational deformations in completely different ways. We also present preliminary ideas for extending and improving these methods.

Elastic/plastic Buckling Analysis of Skew Thin Plates based on Incremental and Deformation Theories of Plasticity using Generalized Differential Quadrature Method
Abstract In this study, generalized differential quadrature analysis of elastic/plastic buckling of skew thin plates is presented. The governing equations are derived for the first time based on the incremental and deformation theories of plasticity and classical plate theory (CPT). The elastic/plastic behavior of plates is described by the Ramberg-Osgood model. The ranges of plate geometries...
متن کاملModelling of Crack Growth Using a New Fracture Criteria Based Peridynamics
Peridynamics (PD) is a nonlocal continuum theory based on integro-differential equations without spatial derivatives. The elongation fracture criterion is implicitly incorporated in the PD theory, and fracture is a natural outcome of the simulation. On the other hand, a new fracture criterion based on the crack opening displacement combined with peridynamic (PD-COD) is proposed. When the relati...
متن کاملA Physically Based Deformation Model for Interactive Cartoon Animation
We present an approach for automatic cartoon-style motion dramatization suitable for interactive realtime animation. The system is built upon a physically based deformation model previously discussed in [GMPR06] and achieves squash-and-stretch cartoon deformation relevant to the current object velocity by controlling the deformations in the physically based model. As an improvement over previou...
متن کاملPREDICTION OF STATIC SOFTENING OF MICROALLOYED STEEL BY THE INTEGRATION OF FINITE ELEMENT MODEL WITH PHYSICALLY BASED STATE VARIABLE MODEL
Abstract Recovery and recrystallization phenomena and effects of microalloying elements on these phenomena are of great importance in designing thermomechanical processes of microalloyed steels. Thus, understanding and modeling of microstructure evolution during hot deformation leads to optimize the processing conditions and to improve the product properties. In this study, finite element...
متن کاملA simple and efficient plasticity-fracture constitutive model for confined concrete
A plasticity-fracture constitutive model is presented for prediction of the behavior of confined plain concrete. A three-parameter yield surface is used to define the elastic limit. Volumetric plastic strain is defined as hardening parameter, which together with a nonlinear plastic potential forms a non-associated flow rule. The use of non-associated flow rule improves the prediction of the dil...
