Investigating the Relative Impact of Different Sources of Measurement Non-Equivalence in Comparative Surveys

open access: yesSurvey Research Methods, 2020
Different factors are known to affect the comparability of multinational, multicultural and multiregional (‘3MC’) survey data. These include factors relevant to the design of the questionnaire in different contexts (such as cultural differences in how a

Infrared spectroscopy of solid CO-CO2 mixtures and layers [PDF]

open access: yes, 2005
The spectra of pure, mixed and layered CO and CO2 ices have been studied systematically under laboratory conditions using infrared spectroscopy. This work provides improved resolution spectra (0.5 cm-1) of the CO2 bending and asymmetric stretching mode ...

Analysis of Mixed-Mode I/II/III Fracture Toughness Based on a Three-Point Bending Sandstone Specimen with an Inclined Crack

open access: yesApplied Sciences, 2021
The crack-propagation form may appear as an arbitrary mixed-mode fracture in an engineering structure due to an irregular internal crack. It is of great significance to research the mixed-mode fracture of materials with cracks.

Investigating interfacial cracks in bi-materials through a 4-point bending model analysis [PDF]

open access: yesTheoretical and Applied Mechanics
This study focuses on examining the failure behavior of interfacial cracks in bimaterial structures. Bimaterials present a unique challenge due to their composition, consisting of two materials that can be homogeneous and isotropic, with a specific ...

Crack tip fields in elastic-plastic and mixed mode I+II+III conditions, finite elements simulations and modeling [PDF]

open access: yesFracture and Structural Integrity, 2015
This paper is devoted to the analysis of the load path effect on I+II+III mixed mode fatigue crack propagation in a 316L stainless steel. Experiments were conducted in mode I+II and in mode I+II+III.

The Effect of Temperature and Heating–Cooling Cycles on Mode I, Mode II and Mixed-Mode I-II Fracture Toughness of Sandstone [PDF]

open access: yesMuhandisī-i manābi̒-i ma̒danī, 2021
In the case of explosions and fires, the rocks undergo a cycle of heating and cooling. For that, first, they are exposed to considerable heat and then cooled after extinguishing the fire.

Crack’s bifurcation in an anisotropic material

open access: yesMATEC Web of Conferences, 2012
The orthotropic of a solid is characterized by the material directions 1→,2→,3→$mathop 1limits^ o ,mathop 2limits^ o ,mathop 3limits^ o $ and corresponds to six main directions of the crack’ distribution 21, 31, 32, 12, 13 and 23 (the first number ...

Extension of the CJP model to mixed mode I and mode II [PDF]

open access: yesFracture and Structural Integrity, 2013
The present authors have previously proposed a novel ‘plastic inclusion’ approach for dealing with the local plasticity which occurs at the tip of a growing fatigue crack.

Testing the asymptotic relation for period spacings from mixed modes of red giants observed with the Kepler mission [PDF]

open access: yes, 2016
Dipole mixed pulsation modes of consecutive radial order have been detected for thousands of low-mass red-giant stars with the NASA space telescope Kepler.
