Meshes Made by Deformational Cutting
Journal of Physics: Conference Series, 2022 Abstract Deformational cutting can be used for manufacturing meshes. A metal or polymer sheet with a thickness of 0.2-0.8 mm is used as blanks when producing meshes. The sheet is tightened on a cylindrical fixture, then finned by the deformational cutting method on both sides without separating chips.

Iterative mesh deformation for dense surface tracking [PDF]
2009 IEEE 12th International Conference on Computer Vision Workshops, ICCV Workshops, 2009 In this paper we propose a new method to capture the temporal evolution of a surface from multiple videos. By contrast to most current methods, our algorithm does not use any prior information on t he nature of the tracked surface. In addition, it does not require sparse features to constrain the deformation but only relies on purely geometric ...

Advanced Engineering Materials, EarlyView.This paper presents a novel approach to reducing oxide layers on metal powders using low‐temperature hydrogen dielectric barrier discharge plasmas at atmospheric pressure. Unlike conventional hydrogen‐plasma reductions, the powders do not contact the plasma directly.

On some interactive mesh deformations
, 2023 Techniques devoted to deform 3D models are an important research field in Computer Graphics. They can be used in differentstages: the modelling phase, the animation process and also during some special simulations. Additionally, some applications may require the manipulation of 3D models under certain restrictions to preserve the volume of the modified

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Stabilized material point methods for coupled large deformation and fluid flow in porous materials
, 2019 The material point method (MPM) has been increasingly used for the simulation of large deformation processes in fluid-infiltrated porous materials. For undrained poromechanical problems, however, standard MPMs are numerically unstable because they use ...

Numerical Exploration of Thermal Shock Resistance in MgO–C Refractories
Advanced Engineering Materials, EarlyView.A mesostructure‐resolved numerical framework is developed to evaluate the thermal shock resistance of MgO–C refractories. By modeling interface debonding under rapid temperature changes and introducing a modified thermal shock parameter that accounts for mesocracks, the study shows how graphite content and aggregate size influence thermal shock ...

A Topology Optimization Framework for the Inverse Design of Nonlinear Mechanical Metamaterials
Advanced Engineering Materials, EarlyView.This work uses topology optimization to design unit cells for mechanical metamaterials with a prescribed nonlinear stress–strain response. The framework adds contact and postbuckling modeling to synthesize microstructures for three highly nonlinear responses, including pseudoductile behavior, monostable with snap‐through buckling, and bistable ...
