3.9.8: Principal States Transformation πŸ”·

With the β€œPrincipal States Transformation”-component one can define a tensor via first and second principal vectors β€œVec1” and β€œVec2” and get the components for a given direction β€œDirX”. This allows to e.g. calculate the bending moments or in-plane forces of a shell for a section perpendicular to β€œDirX”. β€œN” specifies the direction normal of a plane onto which β€œVec1” and β€œVec2” get projected before performing the transformation.
