39、 Knowledge of the resistance of these materials to this type of behaviour is therefore very important.In practice, tearing can result from very different circumstances; hence the large number of test methods that have been developed in order to predict the behaviour of materials in various situation
40、s.The ISO 4674 series deals with initiated tearing, i.e. the propagation of a tear from an initiating cut.This part of ISO 4674 describes two methods using a tensile-testing machine at constant rate of elongation. ISO 4674-2 describes a dynamic method using the kinetic energy of a falling pendulum.D
