Modulus elasticity is the ratio of stress to strain of a material in deflection (say in a beam) and is sometimes called ‘young’s modulus’ the higher the values of young’s modulus the better. The elastic modulus calculated for each combined with the mid-span deflection recorded under the elastic loading indicates the benefits caused by bonding the steel tendon although a slight increase in stiffness was recorded within the u series, when compared to the c series, both the r and b series show a significant increase in stiffness that. 20 - data analysis the purpose is to calculate mechanical properties of steel, namely modulus of elasticity, yield stress, ultimate stress, resilience, fracture. What is the young modulus it is the modulus of elasticity this means it is a number which represents how easy it is to deform (stretch a material) when a material. Shear modulus (modulus of rigidity) is the elasticity coefficient for shearing or torsion force. A finite element model is developed to analyse, as a function of volume fraction, the effects of reinforcement geometry and arrangement within a timber beam the model is directly validated against experimental equivalents and found to never be mismatched by more than 8% in respect to yield strength predictions yield strength increases.

Young modulus if you plot a stress against strain of a material with the (linear) elastic behaviour, you get a straight line ie stress is proportional to strain the gradient of the above straight line is the young's modulus, e and e is constant and does not change for a given material, no matter what the size of the sample we test.
