...Allen Kim; Lily Vu; Tony Chung; David Song; Junlan Wang Additive manufacturing (AM) has emerged as a crucial technology in recent decades, particularly within the aerospace industry. However, the thermally cyclic nature of these processes introduces significant variations and defects...

... microstructural disorder of biopolymer networks, which limits the ability to tune their mechanical properties. To fill in this gap, we developed a method to generate computer models of aperiodic fiber networks mimicking type I collagen ready to be submitted for additive manufacturing. The models of fiber networks...

... thickness, number of domains at the cross section, and transverse bridges connecting adjacent walls. To specifically study the effect of these structural characteristics on the mechanics and anisotropic compressive properties of scaffolds, we utilize additive manufacturing, i.e., 3D printing, to fabricate...

... through-thickness variation, the crack was forced to bow outward around the thickness change when exiting the inclusion, creating additional toughening. heterogeneous materials fracture toughness phase-field method additive manufacturing elastic mismatch It is understood...
