Complex training: The effect of exercise selection and training status on postactivation potentiation in rugby league players [PDF]

open access: yes, 2017
This study compared the postactivation potentiation (PAP) response of the hex bar deadlift (HBD) and back squat (BS) exercises. The PAP response between different levels of athletes was also compared.

SKITTER foot design [PDF]

open access: yes
A mechanical design team was formed to design a foot for the lunar utility vehicle SKITTER. The primary design was constrained to be a ski pole design compatible with the existing femur-tibia design legs.

Correlation Between P-wave Velocity and Strength Index for Shale to Predict Uniaxial Compressive Strength Value

open access: yesMATEC Web of Conferences, 2017
Seismic refraction survey is a non destructive method used in site investigation to identify the seismic velocity subsurface strata. Although it is widely known, the reliability of the result is still doubtable for some reason as well as due to an ...

Point defect effects on tensile strength of α−zirconium studied by molecular dynamics simulations

open access: yesNuclear Materials and Energy, 2019
Vacancy, interstitial, and Frenkel pair effects on the tensile strength of α−Zr are studied by molecular dynamics simulations. The uni-axial tensile load is along [0001] direction of the α−Zr samples.

Mechanical properties of Michigan Basin's gypsum before and after saturation

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2019
The stability analysis of an abandoned underground gypsum mine requires the determination of the mine pillar's strength. This is especially important for flooded abandoned mines where the gypsum pillars become saturated and are subjected to dissolution ...

Estimation of uniaxial compressive strength from point load strength, Schmidt hardness and P-wave velocity

open access: yesBulletin of Engineering Geology and the Environment, 2008
Uniaxial compressive strength is considered one of the most important parameters in the characterization of rock material in rock engineering practice. The study investigated correlations between uniaxial compressive strength and point load index, P-wave velocity and Schmidt hardness rebound number together with the effects of core diameter size.

Transverse flexural tests as a tool for assessing damage to PMR-15 composites from isothermal aging in air at elevated temperatures [PDF]

open access: yes
To date, the effect of thermo-oxidative aging on unidirectional composite mechanical properties has been monitored by the measurement of interlaminar shear strength (ILSS) and either three or four point longitudinal flexural strength (LFS) of the ...

Impact of Sand Grain Size on the Mode I Fracture Toughness and Compressive and Tensile Strength of Artificial Sandstones

open access: yesAdvances in Civil Engineering
Texture and mineralogical composition of rocks have a significant impact on their mechanical properties. Grain size is a crucial textural property of sandstones, as it significantly influences their physical and mechanical characteristics.
