Analysis of additively manufactured PLA containing notches using Failure Assessment Diagrams

This paper provides a methodology for the estimation of load-bearing capacity additively manufactured (AM) PLA specimens that may be applied to both cracked and notched conditions. The is based on use Failure Assessment Diagrams (FADs), which are, in practice, main fracture-plastic collapse assessment tool provided by structural integrity procedures. When dealing with notch-type defects, requires, additionally, application notch correction it Theory Critical Distances (TCD) Creager-Paris stress distribution ahead crack-tip. results show FAD (alone, conditions, or combination TCD conditions) can successfully this AM polymer.
