Microstructure-topology relationship effects on the quasi-static and dynamic behavior of additively manufactured lattice structures

Additively-manufactured PEEK/HA porous scaffolds with highly-controllable mechanical properties and excellent biocompatibility

“…In addition to the bioactivity, the mechanical properties of the scaffolds significantly affect the load transmitting and tissue growth [19][20][21][22] . The micro-structure of the scaffolds such as pore architecture [23,24] , pore size [25] and porosity [26,27] , impacted the mechanical performances of the scaffold greatly. Liang [28] et al fabricated square, hexagonal and wheel-shaped porous scaffolds by 3D printing, finding that the square scaffolds exhibited better mechanical strength and fatigue properties.…”

Shock compression behavior of stainless steel 316L octet-truss lattice structures

“…Thus, the mechanical behavior of lattice structures inherently depends on both unit cell topology and base material. Strain-rate effects have been observed in two regimes: (1) at moderate to high strain-rates (1000/s), lattice structures J o u r n a l P r e -p r o o f Journal Pre-proof show strain-rate-dependent mechanical behavior consistent with the base parent material [11][12][13]; and (2) at very high strain-rates or impact velocities, lattice structures exhibit a compaction shock wave [14,15] similar to that in cellular materials [16].…”

BCC lattice cell structural characterization

“…In this large portion of fields, low-density and relatively complex geometries are needed in order to fulfill the requirements. One of the main advantages of this manufacturing technique is to deal with lattice structures made by unit cells Maskery et al (2018), Hazeli et al (2019), Jin et al (2019), Aboudi and Gilat (2005), Wallach and Gibson (2001), Shen et al (2010), Liu et al (2006), Zok et al (2004). For instance Lei et al (2019) made a study concerning about the practical influence of the geometrical properties of two similar cells, the BCC and the BCCZ one, showing how these geometrical parameters afflict the mechanical behavior of the whole structure.…”
