Fatigue Crack Modeling Of Additively Manufactured Abs Cantilever Beam, Jason W. Booher
Fatigue Crack Modeling Of Additively Manufactured Abs Cantilever Beam, Jason W. Booher
Mechanical Engineering ETDs
A Finite Element model was developed to model crack development in additively manufactured additively manufactured Acrylonitrile Butadiene Styrene (ABS) cantilever beams. Experiments were conducted on the beams with both shock and random vibration base excitations. The base excitations induced damage in the beam that cause crack propagation. It was observed during the cracks developmental stages that an increase in damping occurred. The proposed Finite Element model also showed similar increases in damping from the addition of Coulomb damping forces.
