Metal-polymer functionally graded materials for removing guided wave reflections at beam end boundaries [PDF]

, 2007
This paper investigates the potential of a metal-polymer functionally graded material (FGM) to remove beam end boundary wave reflections that produce complicated interference patterns in the response signals used for guided wave damage identification ...

Effect of Unit Cell Topology on Dielectric Properties of Periodic Lattice Materials Used for Functionally Graded Insulation

High Voltage, EarlyView.
ABSTRACT Periodic lattice material (PLM) is an innovative material system capable of rapidly and efficiently constructing functionally graded materials (FGMs). Among various PLM structures, triply periodic minimal surfaces (TPMS) exhibit numerous advantages, making TPMS‐based lattice materials a potential candidate to electrical FGMs.

A parametric study on the buckling of functionally graded material plates with internal discontinuities using the partition of unity method

, 2013
In this paper, the effect of local defects, viz., cracks and cutouts on the buckling behaviour of functionally graded material plates subjected to mechanical and thermal load is numerically studied.

A Thermal‐Dependent Conductivity Coating for Surface Charge and Electric Field Mitigation Under Electrothermal Coupling Field

High Voltage, EarlyView.
ABSTRACT The problem of gas–solid interface charge accumulation is an important reason for distorting the surface electric field and then inducing surface discharge. The temperature gradient distribution formed on the spacer during the operation of a gas‐insulated transmission line (GIL) will aggravate the surface charge accumulation, further ...

Dynamic responses of an inclined FGSW beam traveled by a moving mass based on a moving mass element theory

Vietnam Journal of Mechanics, 2019
Dynamic analysis of an inclined functionally graded sandwich (FGSW) beam traveled by a moving mass is studied. The beam is composed of a fully ceramic core and two skin layers of functionally graded material (FGM).

Ceramic Production and Geodiversity in Iron Age Iberia: An Archaeometric Study of Pottery from Castrejón de Capote (SW Spain)

Archaeometry, EarlyView.
ABSTRACT The hillfort of Castrejón de Capote is one of the best investigated settlements of Late Iron Age southwest Iberia. Located in the territory that the classical sources attributed to the Celtici, it was occupied between the early 4th and the 1st centuries bce.

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 ...

Tooth Sensitivity, Bleaching Efficacy, and Quality of Life in Young People and Adults: A Stratified, Randomized Bi‐Center Study

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives This study compared tooth sensitivity, bleaching efficacy, and the impact on oral health‐related quality of life between at‐home and in‐office tooth bleaching in adults and young individuals. Materials and Methods Eighty participants, 40 young people (14–20 years) and 40 adults (40–60 years), were randomly assigned to receive either
