What specific weight, elastic modulus and wave speed should be entered into the PDA / GRLWEAP when testing / analyzing ductile cast iron piles (DYWIDAG brand)?

The recommended parameters for the material of these piles are:

•Specific weight: 69.2 kN/m3 (442 lb/ft3)

•Elastic Modulus: Between 140 and 165 GPa or 20,000 to 24,000 ksi

•Wave speed: 4,400 to 4,800 m/s (14,500 to 15,900 ft/s)
