Dictionary with the following keys

youngs_modulus: Young’s modulus (or Young modulus) in GPa is a mechanical property of solid materials that

measures the tensile or compressive stiffness when the force is applied lengthwise.

poissons_ratio: In materials science and solid mechanics, Poisson’s ratio ν (nu) is a measure of the Poisson

effect, the deformation (expansion or contraction) of a material in directions perpendicular to the specific direction of loading.

bulk_modulus: The bulk modulus (K or B or k) in GPa of a substance is a measure of the resistance of a

substance to bulk compression.

shear_modulus: In materials science, shear modulus or modulus of rigidity in GPa, denoted by G, or sometimes

S or μ, is a measure of the elastic shear stiffness of a material and is defined as the ratio of shear stress to the shear strain.
