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

Mixed-mode impedance and reflection coefficient of two-port devices [PDF]

open access: yes, 2012
From the point of view of mixed-mode scattering parameters, Smm, a two-port device can be excited using different driving conditions. Each condition leads to a particular set of input reflection and input impedance coefficient definitions that should be ...

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 ...

Mixed-Mode Shell-Model Calculations [PDF]

open access: yes, 2002
A one-dimensional harmonic oscillator in a box is used to introduce the oblique-basis concept. The method is extended to the nuclear shell model by combining traditional spherical states, which yield a diagonal representation of the usual single-particle

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.
