Mechanical Properties Analysis and Optimal Design of Pyramid Lattice Composite Structures
摘要
Abstract
Pyramid lattice composite material is a new lightweight and high-strength material, which shows the extremely potential application for its advanced multi-function properties including the thermal insulation, vibration isolation and electronic shielding, etc. The flat compression and shear model of the pyramid lattice cell is established with the finite element software ABAQUS to analysis the equivalent flat compression and shear performances. The theoretical results of the flat compression and shear modulus are calculated after setting up the multi-ply lattice composite model, and compared with the numerical results of the equivalent flat compression and shear modulus depending on the flat compression and shear stiffness from ABAQUS. The correction of the numerical simulation is verified. Then, for the symmetrical-ply lattice composite structure, the optimal results of different layer number, ply angle and tilt angle are obtained for flat compression and shear model through the numerical simulation by the finite element software ABAQUS.关键词
