Optimization of Lattice Sandwich Structure With Sequential Quadratic Programming Algorithm

To study the influence of the core cell on the structural carrying capacity, in this paper, lattice sandwich structure optimization model was established, which was elaborated by tetrahedron unit cell of sandwich structure. For the purpose of verifying the effectiveness of the optimization model and the solution, a sandwich tic-tac-toe beam structure with the goal of maximizing the stiffness of the structure was optimized by using the method of sequential quadratic programming.
