Fracture development and deformation behavior of zeolite-filled high density polyethylene annealed composites in the plane stress fracture

This study explores the zeolite-high-density polyethylene (HDPE) composites annealed at 90C which was investigated to obtain the crack growth and deformation behavior under tensile loading until the specimen was completely broken. Crack growth and deformation were obtained from the double-edge-notched tensile (DENT) test. At each stage of fracture development, the value of fracture energy consumed was determined based on the energy partitioning concept. The deformation is assessed at each stage of the fracture process both at the crack initiation and crack propagation. The results describe that the crack grows in a similar way, and the deformation behavior involved varies with the essential work of fracture (EWF) values for each stage of crack growth.
