查询词典 Young's modulus

Based on Three Gorges Project, the following aspects about the three typical embedding manners are studied:(1) The border condition of cyclic symmetry is applied to the finite element models with contact among cushion layer, penstock and concrete. The effects of elastic modulus, thickness and placement extent of cushion layer on the stress of its around concrete are analyzed.
