Material Characterization and Numerical Techniques for Accurate Prediction of Snow-Tire Interactions
… of in-situ devices such as the CTI penetrometer, Clegg hammer, and vane-cone device compared method performance in terms of accuracy, stability, and computational efficiency. The hybrid SPH-FEM method demonstrated the best performance. Additionally, a finite element analysis (FEA) model of the …

Can the natural turf pitch affect injury risk and performance within elite football?
… and practical objective measure of hardness (Clegg Hammer 2.25kg), evaluated its reliability and formulated a protocol for its use. This new protocol was then used within the remaining chapters to evaluate the pitch hardness. Chapter 5 established the temporal and spatial variation of natural …

Investigation of Equestrian Arena Surface Properties and Rider Preferences
… deceleration, shear modulus and hysteresis), Clegg Hammer (hardness) and Torque Wrench (traction) were used as a suite of mechanical tests to investigate the effects of three different moisture levels (6.83 ± 1.01%, 17.45 ± 0.76%, 21.19 ± 0.9%) and three different surface densities …

The effects of preliminary unaffiliated dressage competitions on the mechanical properties of a synthetic equestrian arena surface
… that were measured were hardness, using a Clegg Impact tester, traction, using a torque wrench and penetrability, using a penetrometer. Each piece of equipment was tested on a prepared, synthetic equestrian surface at Myerscough International Arena, in order to determine the method of use …

Compacted Snow Testing Methodology and Instrumentation
Snow is a complex material that is difficult to characterize especially due to its high compressibility and temperature-sensitive nonlinear viscoelasticity. Snow mechanics has been intensively investigated by avalanche and army researchers for decades. However, fewer research studies have been …

Use of the Clegg Impact Soil Tester to Access Rutting Susceptiblity of Cement-Treated Base Material Under Early Trafficking
… research were to examine the correlation between Clegg impact values (CIVs) determined using a heavy Clegg impact soil tester and rut depths measured in newly constructed CTB and subsequently establish a threshold CIV at which rutting should not occur.The experimental work included field testing …
