Static bending modulus of elasticity
WebThe proportionality constant in this relation is called the elastic modulus. In the linear limit of low stress values, the general relation between stress and strain is. stress = (elastic modulus)×strain. stress = (elastic modulus) × strain. As we can see from dimensional analysis of this relation, the elastic modulus has the same physical ...WebThe values of conventional strength in the static bending test (f M) and conventional modulus of elasticity in bending (E M) were obtained following the recommendations of ABNT NBR 7190 (1997).
