Abstract

The fracture behavior of woven fiber glass-reinforced low-density polyethylene thermoplastic composite having a middle tension specimen with inclined through-thickness cracks under static loading is studied in this article. Through the experiments, the topics crack growth, crack opening displacement (COD), stress intensity factors, and fracture toughness are studied. Crack growth amount and COD values are used as a damage parameter factor for crack geometry calculations. The consequent results of the experiments are inspected with J-integral method and stress intensity factor. Load-elongation and load-crack mouth opening displacement, the strain energy release rate-crack growth amount, stress intensity factor-crack growth amount graphics were drawn as the material properties under consideration. © 2010 The Author(s).
