A comprehensive finite element model was established to calculate shear stress in the runner regions during die filling, and a novel mathematical model of grain breakup was proposed to quantitatively analyze ESCs fragmentation through different runners.

The influence of porous structures with small unit cell on scaffold formability and mechanical properties was investigated through compression, torsion tests as well as finite element simulations. Consequently, gyroid scaffolds exhibit optimal formability with the lowest porosity and pore deviation. With the same porosity, gyroid and RD scaffolds exhibit lower compressive strength than cubic and CHC scaffolds, yet their torsional properties show an inverse relationship. Moreover, gyroid scaffolds possess the highest torque but the lowest compressive strength and elastic modulus. The gyroid scaffold with 60% porosity shows a modulus of 3.96 GPa, matching bone modulus of 0−30 GPa. Its compressive strength reaches 176.3 MPa, exceeding that of bone by 100 MPa.

The fatigue strength of the welded joints was essentially lower than that of the aluminum base material. This observation was attributed to the easy nucleation of the fatigue crack at the end section of the unwelded interface. Accordingly, the weld fatigue behavior was governed by crack propagation.
