a. Relationship of CBR and Dynamic Cone Penetrometer (DCP) Index: The dual mass Dynamic cone Penetrometer (DCP) is a method for estimating in-place stability from CBR correlations. As shown in Figure 6E-1.05, the dual mass DCP consists of an upper and lower 5/8 inch diameter steel shaft with a steel cone attached to one end.

Therefore, the purpose of this study was to systematically review mechanical testing of articular cartilage and cartilage repair constructs over the past 10 years (January 2009–December 2018), to highlight the most common testing configurations, and to identify key testing parameters. For the most common tests, key parameters identified in ...

This document reports on a lab experiment conducted by students to calibrate a Bourdon pressure gauge. The objective was to calibrate the gauge by applying known weights to a piston-cylinder system and measuring the resulting pressures. Weights were added and removed to obtain loading and unloading pressure readings. Percentage errors …

Abstract: In this work, we determine the optimal geometry of complex trochoid polygon contours with respect to the stresses occurring in the shaft-hub connection. For this purpose, we carried out FEM calculations to investigate the influence of the different contour types as well as the variable parameters eccentricity and number of carriers on the level …

This paper presents a theoretical analysis of the elastic general instability of two swedged-stiffened cylinders subjected to hydrostatic pressure loading and the effect of varying the angle of the cone section on this general instability pressure. From the standpoint of buckling pressure, available cabin space, and weight reduction, a …

The pressure in a static fluid arises from the weight of the fluid and is given by the expression P = ρgh P = ρ g h.

Moreover, under the sliding friction and wear conditions in the corrosive environment, the increase of the efect of hard particles on the material surface caused the pressure and temperature on ...

The purpose of this study is to investigate the effects of Reynolds number (Re) and Cone angle (2θ) on the Pressure Recovery Coefficient (PRC) of the diffuser. It also borders on comparing the advantages and disadvantages of the theoretical, experimental and computational analysis of a diffuser with different cone angles. The above aims, were …

Introduction. In the Cone Penetration Test (CPT), a cone on the end of a series of rods is pushed into the ground at a constant rate and near-continuous measurements are made of the resistance to penetration of the cone and of a surface sleeve. Figure 2 illustrates the main terminology regarding cone penetrometers.
