Web1 jan. 2024 · Fig. 1 gives an example of experimentally determined values of the elastic modulus E exp Δ l as well as the analytical curves of the uncertainty in the elastic modulus W E Δ l, determined using equations (21), (22).The asymptote of the curves is based on the reference value of the elastic modulus for the tested material (in this case E = 210 G P a). WebModulus of elasticity is a measure of the stress–strain relationship and is an important parameter in the evaluation of the deformation response of concrete under working loads. The load-deformation behaviour of concrete is in fact non-linear, though generally in practice, an elastic modulus is adopted for convenience.
