Fatigue Delamination Behavior of GFRP Composites under Mixed-Mode I/II Loading [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 1999
Delamination is a severe threat to the wide use of composite laminates in primary structural applications. Delamination grows under fatigue loading and leads to structural failure. Very few studies exist on mixed-mode delamination on carbon fiber however

Study on Winter Comfort Temperature in Mixed Mode and HVAC Office Buildings in Japan

open access: yesEnergies, 2022
Comfort temperature is important to investigate because the chosen office indoor temperatures affect the energy used in a building, and a thermally comfortable environment makes the occupants be more productive.

Is there an association between survey characteristics and representativeness? A meta-analysis

open access: yesSurvey Research Methods, 2018
How to achieve survey representativeness is a controversially debated issue in the field of survey methodology. Common questions include whether probability-based samples produce more representative data than nonprobability samples, whether the response ...

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 ...

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.
