Two-dimensional (2D) honeycomb ferromagnets, such as monolayer chromium-trihalides, are predicted to behave topological magnon insulators - characterized by an insulating bulk and topologically protected edge states, giving rise a thermal Hall effect. Here we report the behavior of magnons in CrI$_3$ under external stimuli, including biaxial uniaxial strain, electric gating, well in-plane out-o...

In this paper, an approach to aeronautical structural design based on reliability analysis is presented. In this way, the concept of level of safety is discussed and methods of its calculation using statistical data are described. Based on the concept of level of safety, a design procedure is proposed. In order to validate this design procedure, two design cases are studied. In the first case s...

Masonry infill has been widely used as building material due to its cost effectiveness and availability.  The failure of these masonry infill walls during the past earthquakes have underscored the importance of ensuring the safety of the infill walls when it is subjected to lateral loads. In-plane and out of plane failures have been observed in many reinforced concrete framed building with maso...

This experiment was conducted to investigate the effect of pre-pubertal plane of nutrition on the skeletal growth, lamb mortality, insulin-like growth factor 1 (IGF-1) concentrations, quantity and quality of colostrum produced in ewe lambs. A total of 40 clinically health Kurdish female lambs (30±8.6 d and weighing 10.2±3.4 kg) were randomly allocated to one of two experimental diets in pre-wea...

Order parameters and phenomenological theory for both high- and low-symmetry biaxial nematic phases are presented and it is predicted that the chiral low-symmetry biaxial phase must be ferroelectric. This conclusion is based on general symmetry arguments and on the results of the Landau-de Gennes theory. The microscopic mechanism of the ferroelectric ordering in this chiral biaxial phase is ill...

This paper investigates the effect of porous microstructure on necking formability ductile sheets subjected to dynamic in-plane stretching. We have developed an original approach in which finite element calculations include actual void distributions obtained from additively manufactured materials are compared with simulations specimen is modeled Gurson–Tvergaard continuum plasticity theory (Gur...

Abstract Especially in the automotive sector, high-strength sheet materials are processed manufacturing industry. These steels often show a pronounced sensitivity to edge cracks. Because of this, many crack testing methods for wide variety stress conditions have been developed describe material. Only hole expansion test according ISO 16630 has standardized. However, standardization some gaps pr...

are compared with the experimental results. In these test results the shape memory alloys behavior as: super elasticity under various temperatures, loading rate effects, asymmetry in tension and pressure, various loops of loading and unloading, hydrostatic pressure effects, different proportional tension-shear biaxial loading and unloading, and also deviation from normality due to non-proportio...
