Finite cell method for functionally graded materials based on V-models and homogenized microstructures

Advanced Modeling and Simulation in Engineering Sciences, 2020
This paper proposes an extension of the finite cell method (FCM) to V-rep models, a novel geometric framework for volumetric representations. This combination of an embedded domain approach (FCM) and a new modeling framework (V-rep) forms the basis for ...

Effect of Idealization Models on Deflection of Functionally Graded Material (FGM) Plate

Journal of Nano- and Electronic Physics, 2023
Функціонально градуйовані матеріали (ФГМ) — це клас композитів, у яких властивості матеріалу поступово змінюються в одному або кількох декартових напрямках, поєднання яких призводить до більш ефективних характеристик, ніж компоненти, взяті окремо. Цей клас композитних матеріалів привернув значну увагу в інженерних галузях, таких як ядерна енергетика ...

Bending Analysis of Thickness‐ and Shear‐Deformable Materially Imperfect Composite Shells With von Kármán‐Type Geometric Nonlinearities

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Geometrically nonlinear static analysis of materially imperfect composite doubly curved shells is investigated via the generalised differential quadrature method. The effects of both shear and thickness deformation are considered through a thickness‐ and shear‐deformable third‐order theory formulated in curvilinear coordinates, while the ...

SFF-Oriented Modeling and Process Planning of Functionally Graded Materials Using a Novel Equal Distance Offset Approach [PDF]

, 2004
This paper deals with the modeling and process planning of solid freeform fabrication (SFF) of 3D functionally graded materials (FGMs). A novel approach of representation and process planning of FGMs, termed as equal distance offset (EDO), is developed.
