Abstract

This paper experimentally determines the stress on the central structural element of a sandwich structure made of two types of truss model: core-filled model and core-spaced model. The sandwich board is fabricated by casting AC4C aluminum alloy. From the experimental results of the three-point mechanical bending and conventional theoretical methods, the stress range of core-filled model was 28.4 to 30.68 MPa and of core-spaced model was 30.71 to 33.17 MPa for the sandwich core structure. Our results validate the use of these models in future research on lightweight structures.
