Anisotropic deformation and failure behaviors of the necked HDPE materials induced by oligo-cyclic loading

Oligo-cyclic loading tests are performed between a fixed nominal macroscopic strain 1.5 and zero force on high-density polyethylene (HDPE) with different microstructural properties (i.e. crystallinity, lamellar dimensions, density of stress transmitters). Based on the results of simultaneous Digital...
