2.3 Elastic Modulus of Concrete 2.3.1 Definition and Determination of Elastic Modulus of Concrete The modulus of elasticity or "Young's Modulus", a very important mechanical property reflecting the capability of concrete to deform elastically, is defined as the slope of the stress-strain curve within the proportional limit of a material.

There is a paper "Post-cracking shear modulus of reinforced concrete membrane elements" on science direct that discusses this. The value of modulus of rupture varies from 11% to 23% of the compressive strength of the same concrete. The average value may be assumed as 15% of the compressive strength, the use of angular aggregate or rough textured aggregate results in higher modulus of rupture than smooth textured aggregates.
