Resumo

In this work the mechanical characterization of natural fiber rope is studied. For this, the festuca dolichophylla fibers are used to manufacture ropes, which are used to build a 28m span historical hanging bridge, with ancient Inka technology called Qeswachaka at the district of Quehue, department of Cusco in Peru.
Twenty-four tests were performed on samples made by various diameters, varying from 30mm up to 130mm, in order to quantify its material constants using the hyperelastic theory, specifically the Neo-Hookean and MooneyRivlin models as well as fitting a polynomic curve. The findings showed that the initial part of the strength-strain curve fit very close to hyperelastic material behavior and can be applied to future modelling of real structures.
