弹性模数

According to two hypotheses: one for the relation between the dynamic complex stiffness and the material dynamic characteristics, another for the relation between the static displacement and the force acting on the element, the predicting formula for rectangular cross section are obtained respectively using the static stiffness formulation from the beam——column theory and the G〓bel method.
