Formula:
The Elastic Constants are fundamental material properties describing a material's response to applied forces. This calculator uses Young's Modulus (E) and Poisson's Ratio (ν) as inputs to derive Shear Modulus (G) and Bulk Modulus (K).
- Young's Modulus (E): Measures a material's stiffness or resistance to elastic deformation under uniaxial stress. It's often expressed in Pascals (Pa), Gigapascals (GPa), pounds per square inch (psi), or kilopounds per square inch (ksi).
- Poisson's Ratio (ν): Describes the ratio of transverse strain to axial strain. It is a dimensionless quantity, typically ranging from 0 to 0.5 for most engineering materials, though it can theoretically range from -1 to 0.5.
- Shear Modulus (G): (also known as Modulus of Rigidity) Measures a material's resistance to shear deformation. The formula used is: G = E / (2 * (1 + ν))
- Bulk Modulus (K): Measures a material's resistance to compression under hydrostatic pressure (uniform pressure from all sides). The formula used is: K = E / (3 * (1 - 2 * ν))
