Mechanical Properties of Polyester Mooring Cables

摘要

The work presents an expression to deal with the stiffness non-linearity of polyester mooring cables. The basis for that is a PhD thesis of the second author and full scale testing of five inch diameter polyester mooring cables. On one hand, weak dependence on the frequency has been detected. On the other hand, the mild to significant dependence on the average load and load amplitude has become clear. Suggestions on how to deal with the expression in a mooring design are also addressed.
