Do not cross post?
Sorry to harp on but this section is for members requiring help with Mathcad. Occasionally collabs will offer additional help in there field. You have uploaded a paper on the design of Dynamic Stiffness and Damping of Piles with no explanation.
To receive any sort of help or guidance I suggest you offer a worksheet and explain were you are struggling. Forum members offer there services on here for free and have limited time to spare.
