Mechanical properties of diamond lattice structures based on main parameters and strain rate

Abstract

Mechanical properties of diamond lattice structures based on main parameters and strain rateThe diamond triply periodic minimal surface structure has a high mechanical property-weight ratio. They can be modified by changing their internal parameters or the material. They are generated using the additive manufacturing (AM) that possibilities the use of various materials for generating zones with different mechanical properties or by modifying their internal parameters.However, the effects of internal parameters in the mechanical properties have not been defined in detail. Furthermore, the strain rate modifies these mechanical properties. In this study, the effects of the internal parameters and strain rate were evaluated and additionally, the failure mechanism of the structures.
