1. A process of modeling an element with a discontinuity to obtain one or more vibrational characteristics of the element with the discontinuity, the process comprising:

  • providing the physical characteristics of the element;

    providing one or more vibrational characteristics of the element without the discontinuity;

    perturbing one or more vibrational characteristics of the element without the discontinuity based on characteristics of the discontinuity;

    calculating nth-order, perturbed differential equations governing one or more vibrational characteristics of the element with the discontinuity, wherein n is 1 or greater; and

    solving the perturbed differential equations to obtain one or more vibrational characteristics of the element with the discontinuity.
