Structures are subjected to loads of bending and fatigue.

摘要

In a structure comprising a first element 2 and a second element 1 respectively with a higher and a lower moduli of elasticity and fixed together (in 3), the surface and the shape of a cross section of a part of the first of these elements are such that the product of the second moment of area of this part of the modulus of elasticity of the first element is approximately equal to or less than the product of the second moment of the surface by the modulus of elasticity of the second element, so that the stress concentrations are reduced when one or the two elements and / or the connection between them are subjected to bending.
