In general, both the Flexural and Tensile Modulus are used as Young’s Modulus of the material under Flexural (bending) and Tensile deformations respectively. For most metals at small strains, there is no much difference between these two values so either of them can be used as Young’s Modulus in simulations. For polymers, due to their nonlinear material behavior, these numbers need not be the same. In that case, it is recommended to use Tensile Modulus as Young’s Modulus of the material.
