Compared with the forward design method through control of geometric parameters and material types, inverse based on target stress-strain curve is helpful for discovery new structures. This study proposes an optimization strategy mechanical metamaterials a genetic algorithm establishes topology energy-absorbing structures desired curves. A series structural mutation algorithms design-domain-independent mesh generation are developed to improve efficiency finite element analysis iteration. The...
This study proposes a novel node-reinforced plate lattice (NRPL) by introducing the variable-thickness design into nodes of simple cubic (SC) lattice. The NRPL specimens are fabricated via laser powder bed fusion (L-PBF) using stainless steel 316 L powders. Compression experiments and numerical simulations employed to investigate mechanical responses deformation mechanisms NRPL. results reveal that exhibits significantly enhanced energy absorption (EA), reduced initial peak stress smooth...
Abstract A novel explicit time integration method is proposed on the basis of cubic b‐spline interpolation and weighted residual method. Its calculation formulation procedure are presented. Accuracy, algorithmic damping, period elongation theoretically numerically solved. The influence two parameters basic properties studied to obtain optimal values for dynamic problems. Various linear nonlinear problems tested demonstrate high efficiency
Abstract The Schwarz primitive triply periodic minimal surface (P-type TPMS) lattice structures are widely used. However, these have weak load-bearing capacity compared with other cellular structures. In this paper, an adaptive enhancement design method based on the non-uniform stress distribution in uniform thickness is proposed to P-type TPMS higher mechanical properties. Two types of designed by adjusting TPMS. One keeps same relative density, and non-enhanced region thickness. Compared...
An explicit time integration scheme for hyperbolic equations is proposed using B-spline interpolation and weighted residual method. It has simple formulation calculation procedure. With one adjustable algorithmic parameter, new higher accuracy when compared with other excellent schemes. New controllable also desirable period elongation which verified by theoretical analysis numerical simulations. Especially, a demonstrative dispersion coupled the corresponding wave propagation demonstrate...
