The usual formula for the elastic modulus E of a crosslinked highly elastic network E = 3 ρRT/Mc involves molecular weight between crosslinks Mc. It has to be modified by several factors such as the fraction not involved in any external stress and the initial molecular weight distribution. ...
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 ...
