penetration resistance

penetration resistance

1. The resistance by a subsoil to penetration by pile, casing, or sampling device; measured by the number of blows of a hammer of specified weight, falling through a specified distance to drive it a specified distance.

Bias tires are also generally easier to repair than radials and, because of the sheer amount of layers, offer the most penetration resistance in the sidewall.
Soil penetration resistance was measured at field capacity using an Eijkelkamp penetrologger (Eijkelkamp, Giesbeek, The Netherlands) during September 2012.
The size of the water penetration section depends on the water pressure and the penetration resistance which is mainly affected by the melt temperature, mold temperature, water delay time, and cavity section [25,32-35].

The physical parameters that are commonly used to characterize soil under pasture include bulk density, porosity (Cardoso, Wanderley, & Souza, 2016; Carvalho, Ruiz, Costa, Passos, & Araujo, 2014), soil penetration resistance (Cubillos et al., 2016; Redin et al., 2017), and soil-water infiltration (Cullotta et al., 2016; Suarez, Navarro, Campos, Flores, & Mejia, 2018).
Similarly, the undrained shear strength of marine clay at South Pars field in Iran was evaluated using cone penetration resistance by Ebrahimian et al.
The total number of strikes was counted to 10 cm interval depth and the soil penetration resistance was calculated by the following formula:
A mortar-setting-time tester was used to measure the pressure values of the expandable slurries with high water content over time, and the pressure values obtained were substituted into the following equation to calculate the penetration resistance of the slurries over time [24]:
Also, the waterproofness of concrete containing fine particles of blast furnace slag improves as the generated calcium-silicate-hydrate (C-S-H) gel improves the pore system and subsequently the sulfate and chloride ion penetration resistance [15-17].
Hasan (2012) found increment in penetration resistance, due to traffic, of 100, 51 and 15% at depths of 10, 20 and 30 cm, respectively, and indicated moldboard plow as the most efficient implement to reduce penetration resistance in the studied soil.
The reduction of soil pores occurs with the traffic of machines due to the pressures applied by the wheels and consequently increases soil penetration resistance (PR).
