Procedia Structural Integrity, 2018 Abstract This paper studies the applicability of the equivalent material concept developed by the author to the fracture of elastoplastic material due to the presence of U-notches. The approach of equivalent material concept consists of simplifying the study of an elastoplastic material reducing it to the linear elastic case with a maximum stress ...

Micro- and macroscopic simulation of periodic metamaterials [PDF]
Advances in Radio Science, 2008 In order to characterize three-dimensional, left-handed metamaterials (LHM) we use electromagnetic field simulations of unit cells. For waves traveling in one of the main directions of the periodic LHM-arrays, the analysis is concentrated on the ...

Experimental Study on the Influence of Coarse Particle on the Yield Stress of Debris Flows
Applied Rheology, 2016 Former studies show that the coarse particle plays a very important role in the determination of the yield stress of fluid-solid mixtures such as debris flows. The characteristics of the coarse particle in these mixtures include particle size, gradation,

Topological carbon allotropes: paradigm shift for materials innovation
, 2019 Topology is a central concept of mathematics, which allows us to distinguish two isolated rings with linked ones. In material science, researchers discovered topologically different carbon allotropes in a form of a cage, a tube, and a sheet, which have ...

FEBS Letters, EarlyView.Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...
