Název v původním jazyce

Mixed mode I-III fracture resistance of stainless steel 316L weakened by V-notches with end holes

Popis výsledku v původním jazyce

Notch fracture resistance of stainless steel 316L is investigated under mixed-mode I/III loading. A previously proposed test fixture, utilized in the past for testing low/medium toughness polymeric and metallic materials, is first modified to make it appropriate for testing significantly tough materials like stainless steel 316L. Then, original fracture tests are carried out on a specific sample weakened by V-notches with end holes (VO-notches) and loaded under different combinations of tension and out-of-plane shear, from which the critical loads and the fracture behaviour are extracted. Due to great strain-hardening and significant strain-to-failure for stainless steel 316L, the Fictitious Material Concept (FMC) is first employed to avoid complexities associated with fracture prediction. Then, FMC is combined with the maximum tangential stress (MTS) and mean stress (MS) criteria to predict the notch fracture toughness values determined experimentally. With approximately 87 % and 86 % accuracy in estimation of the mean experimental results, both combined criteria, called FMC-MTS and FMC-MS, are revealed to be successful.
