What is Plastics. Determination of tension-tension fatigue crack propagation. Linear elastic fracture mechanics (LEFM) approach about?

This standard BS ISO 15850:2014 Plastics. Determination of tension-tension fatigue crack propagation. Linear elastic fracture mechanics (LEFM) approach is classified in these ICS categories:. 83.080.01 Plastics in general. This International Standard specifies a method for measuring the propagation of a crack in a notched specimen subjected to a cyclic tensile load varying between a constant positive minimum and a constant positive maximum value. The test results include the crack length as a function of the number of load cycles and the crack length increase rate as a function of the stress intensity factor and energy release rate at the crack tip. The possible occurrence of discontinuities in crack propagation is detected and reported. The test can be also used for the purpose of determining the resistance to crack propagation failure. In this case, the results can be presented in the form of number of cycles to failure or total time taken to cause crack propagation failure versus the stress intensity factor (see Annex A). The method is suitable for use with the following range of materials:. rigid and semi-rigid thermoplastic moulding and extrusion materials (including filled an
