Incremental Polygonization of Implicit Surfaces

Graphical Models, 2000
This paper describes an incremental polygonization technique for implicit surfaces built from skeletal elements. Our method is dedicated to fast previewing in an interactive modeling system environment. We rely on an octree decomposition of space combined with Lipschitz conditions to recursively subdivide cells until a given level of precision is ...

Subdivision interpolating implicit surfaces [PDF]

Computers & Graphics, 2003
Abstract Interpolating implicit surfaces using radial basis functions can directly specify surface points and surface normals with closed form solutions, so they are elegantly used in surface reconstruction and shape morphing. This paper presents subdivision interpolating implicit surfaces, a new progressive subdivision tessellation scheme for ...

DigiChrom: A Domain Ontology for Semantic Representation of Trivalent Chromium Platings and Its Large Language Model‐Based Alignment With Multiple Mid‐Level Ontologies

Advanced Engineering Materials, EarlyView.
Digitalizing electroplating requires both domain knowledge and interoperability. This work introduces PlatOn, a domain ontology for trivalent chromium plating and coating characterization, and a hybrid pipeline that aligns it to a mid‐level reference ontology by combining eight similarity metrics with language model reasoning. Expert‐validated mappings

Implicit Uniform Rational Spline Reconstruction Method With Regularization Term

IEEE Access
To improve the accuracy of implicit curve reconstruction and reduce the occurrence of supplementary zero-level sets during the reconstruction process, we propose an implicit curve fitting method with a regularization term based on uniform rational B ...

Elastoplastic analysis by return-mapping method with rigorous loading criterion for extended subloading surface model

Nihon Kikai Gakkai ronbunshu, 2019
The extended subloading surface model is capable of describing cyclic loading behavior accurately. The elastoplastic deformation analysis by the finite element analysis can be executed efficiently by the complete implicit stress integration method with ...

Fiber Bundle Topology Optimization for Surface Flows

Chinese Journal of Mechanical Engineering
This paper presents a topology optimization approach for the surface flows on variable design domains. Via this approach, the matching between the pattern of a surface flow and the 2-manifold used to define the pattern can be optimized, where the 2 ...

From Geometry to Function: Programmable Mechanical Response in 3D‐Printed Adipose‐Inspired Soft Metamaterials

Advanced Functional Materials, EarlyView.
Geometry‐driven design of soft cellular metamaterials is systematically investigated by combining experiments, finite element modeling, and statistical prediction. The study quantifies how unit cell geometry and material properties govern stiffness, instability, densification, and energy absorption.

A fully implicit second order method for viscous free surface Stokes flow – application to glacier simulations [PDF]

Geoscientific Model Development
We present a fully implicit finite element method for viscous free surface Stokes problems which are common in glaciology and geodynamics. Standard fully implicit iterative solvers diverge for such problems when using large time steps. We address this by
