Modal expansion method for eigensensitivity with repeated roots

Extensions to the modal expansion eigensensitivity procedure for self-adjoint systems originally formulated by Fox and Kapoor are presented. The extensions allow for the computation of sensitivity information for mode shapes associated with repeated roots and repeated root derivatives.
