In-air Tensile Load-strain Behaviour of HDPE Geogrids Under Cyclic Loading

The paper describes a series of wide-width monotonic and multistage tensile tests on HDPE extruded uniaxial geogrids with different tensile stiffness. The cyclic tensile tests have been performed using a multistage procedure varying the pre-stress tensile load, the cyclic tensile loading amplitude and the frequency. The influence of these parameters on the residual strains (defined as the strain value when cyclic loads returns to the pre-stress load) has been analysed.
