The usual formula for the elastic modulus E of a crosslinked highly elastic network E = 3 蟻R T/ Minvolves molecular weight between crosslinks M. It has to be modified by several factors such as the fraction not involved in any external stress and the initial molecular weight distribution. ...
(Paul, 1960) makes simplifying geometrical assumption of the regular equidistant distribution of the identical carbide crystals with the cubic shape and no carbide-carbide contacts and arrives at the approximate "strength of materials" type of formula for the dependence of the Young's modulus of ...
Elastic modulus is defined as the ratio of stress to strain below the proportional limit. It is a measurement of a material’s rigidity or stiffness. The slope of the stress-strain curve in the range of linear proportionality of stress to strain in terms of the stress-strain curve is the ...
Influence of interphase characteristics on the elastic modulus of unidirectional glass-reinforced epoxy composites: a computational micromechanics study This article briefly discusses the role of interphase in the elastic moduli of unidirectional fiber-reinforced polymer composite materials.

Two types of deterministic and stochastic cascading algorithms are employed to synthesize the multifractal fields, and then a mathematical formula is proposed to perform the conversion from the intensity of a multifractal field to the local elastic modulus of a multifractal porous material. Furthermore,...
