Quasi-Static and Dynamic Fracture Behaviors of Additively Printed ABS Coupons Studied Using DIC: Role of Build Architecture and Loading Rate

Dual-Notch Void Model to Explain the Anisotropic Strengths of 3D Printed Polymers

“…Also, triangle notch voids were observed in 3D printed polymers [5]. Our modeling can be extended to dynamic failure strengths [26]. Cole et al found that during the printing process, the butadiene phase of ABS migrates away from the raster interfaces and the styrene-acrylonitrile (SAN) phase migrates to the interface and a non-homogeneous microstructure exists [27].…”

Evolution and new horizons in modeling crack mechanics of 3D printing polymeric structures

“…Isaac and Tippur [129] applied the quasi-static and impact fracture tests for FDM ABS specimens with the specific interest to the role of two different print architectures orientations. The test results showed that crack propagated and grew along the printing orientations.…”
