In this note we propose a finite element method for incompressible (or compressible) elasticity problems with discontinuous modulus of elasticity (or, if compressible, Poisson's ratio). The problem is written on mixed form using P 1-continuous displacements and elementwise P 0 pressures, leading ...

Ans:Modulus of elasticity is defined as the ratio of longitudinal stress and longitudinal strain. Since the strain does not have any unit, it will have the unit of stress. The SI unit of this modulus is the Pascal \(\left({\rm{Pa}} \right).\)...
An elastic modulus, or modulus of elasticity, is the mathematical description of an object or substance’s tendency to be deformed elastically (i.e., nonpermanently) when a force is applied to it. From: Encyclopedia of Biomedical Engineering, 2019 ...

These problems complicate the determination of the modulus of elasticity characterizing the material's stiffness under a uni- axial state of stress. Theoretically, the influence of the lateral forces at the specimens' end faces vanishes with increasing specimen length, but the maximum size of the ...

A “Tangent” tensile modulus value is the slope of the elastic region of the stress-strain curve and is also known as Young's Modulus, or the Modulus of Elasticity. A “Secant” tensile modulus value is the slope of a line connecting the point of zero strain to a point on the stress...
