Abstract
The objective of this study is to investigate the fatigue and fracture behavior of woven steel reinforced high density polyethylene (HDPE) thermoplastic composite having a middle tension (MT) specimen with through-thickness crack. The composite material was manufactured from bi-directional woven Cr—Ni steel fibers and HDPE with a fiber volume fraction (Vf) of 0.04. The crack initiation, damage behavior, fatigue crack-growth rate (da/dN), stress intensity factors (▵K), strain energy release rates (▵G), and fracture toughness (KIC) were determined in the study. Moreover, ▵G values were obtained by using linear elastic fracture mechanics (LEFM) and compliance methods, and the results were compared with each other. Also, da/dN—▵K and da/dN—▵G were plotted for determining fracture behavior under fatigue loading of the composite material.
