Problem statement: In engineering design, stress affects the size of structural member. A suitable topology of structure should be designed to optimize the stress. Approach: This study presents an alternative topology of truss-like core sandwich beam referred to here as bi-directional corrugated-strip core topology. A finite element method is used to study the stress response of three point loaded truss-like core sandwich beams. Two kinds of core topologies: A truss core and a bidirectional corrugated-strip core are chosen to be analyzed and compared to each other. Results: The results showed that the bi-directional corrugated-strip core topology provided less surfaced normal stress than the truss core topology. Conclusion: From the finding, the stress of truss-like core sandwich beam can be optimized by arranging the core in the alternative bidirectional corrugated-strip core topology.
