Young's Moduli are close enough to their actual values to determine that our apparatus to ﬁnd Young's Modulus is only an approximate way to ﬁnd the Young's Modulus of a material. Future Work For future work we wish to accomplish with the Young's Modulus is to determine Young's Mod-ulus by testing variables with a standing wave set-up.

Young's modulus is a measure of stiffness of an elastic material and is a quantity used to characterize materials. It can vary considerably depending on the exact composition of the material. If the beam is loaded at its mid-point, the depression produced will not form an arc of a circle. This type of bending is called non-uniform bending.

Metallurgical slag is a valuable, but insufficiently used by-product especially from the production of iron and steel.This paper investigates the potential of employing the mixtures of blast furnace slag and naturally occurring minerals in production

Jun 04, 2015· Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0).Lithology is commonly derived during log analysis, so m may be estimated (Table 1).What is needed still is an initial measure of rock strength provided by C 0. C 0 can be estimated from porosity or sonic velocities, but …

bal values of Young's modulus (E in GPa) are basalt, 50; diabase, 88; andesite, 31; and mudstone, 1 (Palmstro¨m& Singh 2001). The types of structures that develop in rocks during large deformation events depend on the nature of applied forces, on physical conditions such as temperature and on the water content of the rock. Increasing the ...

Jun 24, 2010· Only λ and shear modulus (μ) appear in Hooke's law and not Young's modulus (E), the bulk modulus (K) or Poisson's ratio (υ). Unfortunately, so far little has been known about the characteristic λ value for each common type of crystalline rocks that constitute the Earth's crust and upper mantle and its variation with pressure (P ...

Apr 01, 2008· Oda (1986) introduced the model which allowed to use second rank crack tensor to calculate values of effective Young's modulus for different directions of seismic waves propagation. Directional changes of effective modulus [E.sup.*] can be present as quotient effective modulus and its isotropic modulus E:

deformation modulus of rock masses was made by Hoek and Diederichs (2006). This chapter presents the most recent version of the Hoek-Brown criterion in a form that has been found practical in the field and that appears to provide the most reliable set of results for use as input for methods of analysis in current use in rock engineering.

1. Scope. 1.1 This test method covers the determination of Young's modulus, tangent modulus, and chord modulus of structural materials, see Fig. 1. This test method is limited to materials in which and to temperatures and stresses at which creep is negligible compared to the strain produced immediately upon loading and to elastic behavior.

flexural strength (sometimes called the modulus of rupture) is calculated as the maximum tensile stress existing on the lower fiber of the beam at peak load. Using simple beam theory and three point loading (Figure 5a), the tensile strength is equal to. CVEN 5768 -Lecture Notes 8 Page 6

Young's modulus of normal diabase and metamorphic diabase equals to 39.5 and 1.52 GPa, respectively. Overall, the physical and mechanical properties decrease significantly once the hard diabase was metamorphosed to chlorite. Moreover, fault develops at the interface with granite. At these sites, the shear sliding is easy to occur and severely ...

The increase in SiO 2, Al 2 O 3, and CaO contents have a positive effect on nanohardness and a negative effect on elastic modulus. After limewater treatment, the nanohardness of limestone was found to have increased, whereas those of the remaining five aggregates (basalt, diabase, granite, RCA, and RCB) had decreased.

Feb 13, 2015· First of all, (kg/cm^2)*10^5 is not the correct unit for Young's modulus, which should be in units of pressure. Pressure is a force over an area, so N*m^-2 or in SI units kg*m^-1*s^-2. Maybe what you were going for was gigapascals, which would be (N/cm^2)*10^5, although a better way to write that would just be (N/m^2)*10^9.

Young s modulus, also referred to as the Young modulus, is a mechanical property of substances that offers insight into the stiffness of that material in its solid form. Young s modulus provides a relationship between the strain on an object (the proportional deformation of an object) and the stress applied on it
