Adaptively Simulating Inhomogeneous Elastic Deformation
In this paper, we present an adaptive approach for simulating elastic deformation of homogeneous and inhomogeneous objects based on continuum mechanics. In typical adaptive simulation approaches, the deforming elastic object is usually subdivided to form a tree structure on the fly. However, they are not directly applicable for inhomogeneous elastic deformation, since the elasticity matrix, whi...
متن کاملAdaptive Deformation Simulation of Inhomogeneous Elastic Objects
ゼリーのような柔らかいもの(もしくは弾性体)の物理 ベースな変形シミュレーションは, 動画やテレビゲームなど の分野において重要である. これまで, コンピューターグラ フィックスの分野において, 弾性体の変形に関する非常に多 くの研究がなされてきた. 質量バネモデルや粒子ベースモ デル [19, 11, 1]は, テレビゲームのようなインタラクティブ なアプリケーションに用いられ, より正確な, すなわち連続 体力学に基づいた FEM(Finite Element Method, 有限要素 法)ベースのシミュレーション手法は, 主に正確さが要求さ れる動画に用いられている. FEM ベースのモデルは, 計算 コストが高いことが知られており, アダプティブ分割法など の多重解像度手法が提案されている [4, 8]. 一般的に多重解像度のアプローチを用いる FEM ベース の手法では,...
متن کاملElastic-Plastic Invariant of Localized Deformation Autowaves
The parameters of localization patterns emerging at the linear stage of work hardening are discussed in the frame of autowave concept. The stress-strain diagrams have been plotted for the test samples of metals exposed to active loading. It is found that the product of phase autowave velocity and length has the same order of magnitude as the product of elastic wave rate and the lattice constant...
متن کاملElastic-plastic Deformation at Finite Strains
In some circumstances, elastic-plastic deformation occurs in which both components of strain are finite. Such situations fall outside the scope of classical plasticity theory which assumes either infinitesimal strains or plastic-rigid theory for large strains. The present theory modifies the kinematics to include finite elastic and plastic strain components. For situations requiring this genera...
متن کاملElastic Image Registration using Parametric Deformation Models
The main topic of this thesis is elastic image registration for biomedical applications. We start with an overview and classification of existing registration techniques. We revisit the landmark interpolation which appears in the landmark-based registration techniques and add some generalizations. We develop a general elastic image registration algorithm. It uses a grid of uniform B-splines to ...
