Energy transmission and dissipation during HVC lead to the uneven pressing force of the powder in the die cavity, which ultimately affects the densification and mechanical properties of powder metallurgy products. This study used the discrete element method (DEM) to monitor the energy transmission and dissipation of the powder system during HVC, investigate the relationship between the dissipation of kinetic energy and the impact energy during the loading stage, and consider the relationship between the strain energy release rate and the impact energy during the unloading stage. The results show that the boundary energy (impact energy) is mainly converted into strain, frictional, and damping energy, of which the kinetic energy is only an intermediate form and its attenuation equation is also obtained. The larger the porosity of the particle system is, the larger the dissipation factor β is, and the more serious the energy dissipation is. It can be found that the release rate of the strain energy gradually decreases with increasing impact energy, and the strain energy is significantly higher than the frictional energy in the green compacts.

“…The elastic modulus and compressive strength of BCC lattice structures also can be enhanced by adjusting the three-dimensional posture and mirror arrays of unit cells [29]. In addition to the change in the geometry of the BCC lattice structure, the mechanical enhancement was also realized by adding the reinforcing component [30][31][32]. For instance, Smith et al [30] added a vertical strut to the BCC unit cell and designed the BCC-Z lattice structure.…”

“…The added struts changed the deformation behavior from bending-to stretchingdominated and significantly enhanced the stiffness and strength [33]. Chapkin et al [31] manufactured the composite BCC lattice structure by filling metallic BCC lattice structures with compressible foam. The compression tests demonstrated that the foam-infilled structure improved the volumetric energy dissipation and energy absorption efficiency by 19% and 12% compared to the unfilled one, respectively.…”

“…Past studies have shown that Ti‐6Al‐4 V trusses are efficient for maximizing specific compressive strength, stiffness, or energy absorption due to their high strength and stiffness at low densities [9]. Mechanical energy is absorbed in the joints via elastic bending of struts which leads to a rapid increase to stiffness [10].…”

The present study focuses on the design and finite element analysis of a novel hip prosthesis comprising truss structures intended to equally distribute the stress along the prosthesis. The prosthesis is designed to suit three different inclination angles of 20°, 40° and 60°. The three designs were subjected to loading conditions that emulate walking, jogging, and cycling activities via finite element simulations. Using the von Mises yield criterion and Goodman relation for fatigue, it is found that the safety factor and the life cycle of the proposed prosthesis design was within the acceptable range. Furthermore, the truss structures incorporated in the prosthesis appear to reduce the stress levels in the femur.
