| Abstract Scope |
A high-throughput fatigue testing apparatus, dubbed the “Goodman Diagram Maker” (GDM), was developed to rapidly establish the safe operating condition of additively manufactured components. The GDM is an extensible test device that uses an electric motor to drive up to six Krouse-type flat-bending specimens. Each test arm can be run at a different mean stress and stress amplitude allowing one to quickly establish the fatigue strength of a material. GDM specimens are manufactured on the same build plate as the part they are intended to qualify and process modeling ensures that specimens destined for the GDM are clones of the critical region of the full-scale part built using process-parameters. |
