The elastic modulus varies over quite a range, depending on the materials in the concrete and their relative amounts. Various numerical schemes exist for determining it, depending on national preference. However, in order to get a result that actually represents the concrete of interest, one should ...

An elastic modulus (also known as modulus of elasticity) is a quantity that measures an object or substance's resistance to being deformed elastically (i.e., non-permanently) when a stress is applied to it.

Properties of common solid materials are divided into following categories: Physical properties : Density, melting and boiling temperature. Mechanical Properties : Including basic mechanical properties, such as elastic modulus, shear modulus, Poisson's ratio, and mechanical strength properties, i.e., yielding stress, ultimate stress, elongation.

Both granite and marble are natural stone. There are 17 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown. For each property being compared, the top bar is granite and the bottom bar is marble.

4.1 This test method is useful for providing engineering values for stress and deflection analysis of stone panels. It is also useful in indicating the differences in flexural modulus of elasticity between various dimension stones and stones of the same type in different loading directions (parallel and perpendicular to rift or bedding planes).

The Young's Modulus (or Modulus of Elasticity) describes the limit for small strains of the rate of change of stress with strain a material is able to support. Many natural stones have a Modulus of Elasticity of around 50 Gpa (which translates to 50.000 N mm -2, depending on the stone), with pure Quartz reaching a Young's Modulus of 71.7 GPa.

Modulus of elasticity (also known as elastic modulus, the coefficient of elasticity) of a material is a number which is defined by the ratio of the applied stress to the corresponding strain within the elastic limit. Physically it indicates a material's resistance to being deformed when a stress is applied to it.

Pore geometry and elastic moduli CREWES Research Report — Volume 15 (2003) 1 Pore geometry and elastic moduli in sandstones John J. Zhang and Laurence R. Bentley ABSTRACT Pore geometry is a difficult parameter to quantify, but it affects the elastic moduli in a fundamental way. The uncertainty in elastic moduli is to a large degree due to the

The modulus of elasticity is a property specific to a given material and in practice is derived through laboratory testing. The modulus of elasticity is defined as stress/st … rain. One would have to apply a force uniformly over a known cross section of a material and monitor the strain utilising strain gauges.

The modulus of elasticity for a material is basically the slope of its stress-strain plot within the elastic range (as shown in Figure 1). Figure 2 shows a stress versus strain curve for steel. The initial straight-line portion of the curve is the elastic range for the steel.

Elastic modulus is not the same as strength; a 12 x 12 mm concrete block has a much higher elastic modulus than the same size block of Douglas fir, but the concrete is weaker than the wood in tension. Figure 1 is a graph of stress vs. strain for apple and potato tissue. The slope of the curve is the elastic modulus of the two materials.
