Deformation

Deformation related to the inflection points of a deformed structural system

δ_{y, z} = |\frac{U_{c} - U_{Li} - (U_{Ri} - U_{Li}) \cdot x}{L}| < \frac{L}{X}

U_c	Deformation of the cross-section
U_Li	Deformation of the left inflection point
U_Ri	Deformation of the right inflection point
x	Coordinate of the cross-section in the local axis system
L	Distance between the left and right inflection points
