Scale-span stress-constrained topology optimization for continuum structures integrating truss-like microstructures and solid material

This paper proposes a stress-constrained topology optimization method for structures integrating truss-like microstructures and a solid material. By utilizing the representative volume element (RVE) method, the truss-like microstructures are equivalent to homogeneous materials. Then, a power-law material interpolation scheme for bi-material, including the solid material and the equivalent material, is constructed. Based on the mechanical...
