Localization and instability in sheared granular materials: role of friction and vibration
Shear banding and stick-slip instabilities have been long observed in sheared granular materials. Yet, their microscopic underpinnings, interdependencies and variability under different loading conditions have not been fully explored. Here, we use a non-equilibrium thermodynamics model, the Shear …

Methodology to predict the strength and stiffness of red alder block pallet connections fastened with helically threaded nails
… of the effect of dynamic loading on the load-slip response of the connection. Analysis of the data included the creation of two envelope curves, the initial and the final (stabilized) curve. The data obtained from the two curves was used to find the “best” model for predicting the strength and …

Evaluation of Gait and Slip Characteristics for Adults with Mental Retardation
… of interventions intended to reduce slip-related falls. A gait analysis was conducted to quantify normal walking and slip response characteristics for adults with MR as well as a group of non-disabled age- and gender-matched peers. Kinetic and kinematic data were collected and a …

The Influence of Occupational Footwear on Slip Responses
Falls in the workplace most often occur due to slips and unsuitable footwear. While industry standardized occupational footwear (OF) is required for the safety of occupational activities, little is known about how OF influences how individuals respond to an unexpected slip. Therefore, the purpose …

Synchroniser analysis and shift dynamics of powertrains equipped with dual clutch transmissions
… This makes use of the clutch friction stick-slip algorithm to model nonlinearity in clutch engagements, with other nonlinearities including mean and harmonic engine torque models and dual mass flywheel with hysteresis. Comparisons between 4 and 15 DOF powertrain models are made, and the …

Static push-out tests and finite element studies on larger diameter shear studs for composite steel bridges
… The static push-out tests generated data on load-slip behavior of the studs to characterize the stiffness, strength, and slip capacity of the studs. The tests explored a number of variables, including stud layout, deck reinforcing details, and stud penetration into concrete deck. Tests were …

The Age-Related Effects of Visual Input on Multi-Sensory Weighting Process During Locomotion and Unexpected Slip Perturbations
… increase instability and increase the risk of slips and falls in older adults. The integration of three sensory systems (visual, proprioceptive, and vestibular systems) and the respective weighting of each are needed to maintaining balance during unexpected slip-induced falls. The visual system …
