Study of fracture mechanisms of multiphase polymers using the double-notch four-point-bending method Academic Article uri icon

abstract

  • The double-notch four-point-bend technique (DN-4PB) is developed to study the fracture mechanisms of multiphase polymers. This technique is found to be effective for an unambiguous determination of the fracture mechanisms and the sequence of toughening events of polymer alloys when fracture occurs. The DN-4PB technique is also found to be especially useful for situations where the quantity of the test material is limited and the testing rate is high. The present study demonstrates the usefulness of the DN-4PB technique in a variety of polymeric systems and testing conditions. Requirements for which the DN-4PB technique becomes useful are also addressed. © 1993 Chapman & Hall.
