Correspondence section means to strengthdesign for combinatorial stem
Yu Hua · 2001
As force is acted on a combinatirial stem that is made of“ kkinds material whose length is“ L the stressσ i of“ imaterial is“ P to the equivalent section area ratio.The stressσ j of the other material will be calculated easily after we gotσ i.We can imunize from supperstatic fixed calculation problem.The correspondence section means can be proved by displacement.In this way, we can get the shearing stress and winding stress of all kinds of combinatorial material.
