Modulus of elasticity : It is a term that comes in calculation when axial force is applied on an object. Modulus of rigidity : It is term that comes when shear force is applied on an object. Bulk modulus : Comes in picture during volumetric strain....
Deformation of the tip is measured by optical microscopy and the resulting displacement compared to a standard curve to obtain the modulus as determined by the Hertz model (eqn [1]).11 By tuning the stiffness of the indenter arm, varying ranges of substrate moduli can be measured. As such,...
Strain: the less strain it faces or less change in length the material experiences due to stress applied, the higher will be young’s modulus Elongation: Inversely proportional to the modulus of elasticity Influence of temperature: Generally speaking, the elastic properties of materials decrease with...
interphase modulusIn this work, the interphase in polymer nanocomposites is modeled as a multilayered part in which the Young's modulus of each layer Ek continuously changes from nanoparticle surface (xk = 0) to polymer matrix (xk = t). The dependency of Ek onxk is analyzed by linear, ...
Young’s modulus (E) is one of the basic geomechanical parameters used in rock engineering in practice. It is determined based on uniaxial compressive test (UCS). However, according to International Society of Rock Mechanics it can be calculated by three different ways: as the tangent, secant ...
A bar made of material whose Young's modulus is equal to E and Poisson's ratio to is subjected to the hydrostatic pressure p. Find: A bar made of material whose Young's modulus is equal to E and Poisson's ratio to µ is subjected to the hydrostatic pressure ...
to be a very prospective shale play, (Smith et al.2010; Imber et al.2014; Hough et al.2014). Here we establish empirical relations between mechanical properties (strength, Young’s modulus) and confining pressure, temperature and strain rate, which are important in the petroleum industry (...
Very recently, the similar method based on the first-principles results has been applied to the elastic stiffness coefficients, and then used to predict the Young's modulus according to the Voigt-Reuss-Hill approach [11,12]. In this work, the end-member of Young's modulus for pure Ti are...
2. The nature of elastic modulus Modulus of elasticity describes the difficulty of elastic deformation of an object or substance under a specific applied load within the elastic range, including Young's modulus (E), shear modulus (G), and bulk modulus (B). It is increasingly hard to trigger...
This can be solved using the definition of Young's modulus, as the ratio of applied stress to compressive or tensile strain. This can be written as: E = stress/strain = (F/A)/(ΔL/L) where F = applied force A = cross-sectional area of the material (the area you would see if ...
