The stiffness of a material is defined by the ratio between stress and strain (Young’s modulus or modulus of elasticity) at the elastic regime of a tensile experiment and describes the resistance to elastic deformation of a material.

Elastic Modulus Measurement 4 Comparison of Methods The elastic stiffnesses of a commercial nickel-base alloy measured by the three most widely used techniques, i.e., static, resonance, and ultrasonic wave method, are presented in Fig. 2. As mentioned above the elastic stiffnesses are determined...
An inverse QCT/FEA method was employed, using an optimization process to minimize the error between the predicted femoral stiffness values and experimental values. We determined optimal coefficients of an elastic modulus equation that was a function of ash density only, and also optimal coefficients ...
In such cases, the elastic modulus of the representative volume element of a material can be altered quite substantially. The relationship between porosity and elastic stiffness as well as its size-dependence across several scales is of importance for several material classes. One example is bone, ...
Elastic modulus (E) is a measure of the stiffness of a material under compression or tension, although there is also an equivalent shear modulus. It is a property of the material and does not depend on the shape or size of the object. ...

3.1 Elastic modulus The empirical equation that proposed by Hoek and Diederichs (2006) for solving E of the in-situ rock mass is utilized, Er,insitu = g0 ⋅ Er (7) 1 − D∕ 2 g0= 0.02 + 1 + e(60+15D−GSIinsitu)∕ 11 (8) where Er, insitu and GSIinsitu are E...
The elastic modulus demonstrated strong depth dependence in all models: Hertz/Sneddon models (no brush taken into account), and when the brush model was applied to the data collected with sharp conical probes. We conclude that it is possible to describe the elastic properties of the cell body ...
