| description | This paper presents a part of development of a non-standard method for
testing of cylindrical test specimens for measurement of fracture properties
of pipeline materials. This method for testing of cylindrical structures
working under pressure is based on determining of fracture mechanics
parameters on SENT (Single Edge Notched Tension) specimens and new PRNT
(Pipe Ring Notched Tension) specimens. In this work, both types of specimens
required for this testing were manufactured from polyamide PA12 by using SLS
(selective laser sintering) additive manufacturing method. Testing of the
specimens is performed on the universal device for testing of mechanical
properties of materials Shimadzu, AGS-X 100 kN. The tensile testing is
accompanied by GOM Aramis 2M system, used for digital image correlation. By
using these two systems, test results are obtained for ring-shaped and SENT
specimens, including forces, displacements and fracture mechanics parameters
CMOD (Crack Mouth Opening Displacement) and CTOD-δ5 (Crack Tip Opening
Displacement obtained by δ5 technique), as well as crack growth.
Repeatability of this process, along with valid result consistency,
represent the basis for further development of the new method, including the
determining of energy-based fracture mechanics parameters: J integral and
stress intensity factor. |
