    Thermal Buckling of 3D Printed Auxetic Core Sandwich Beams
    (Springer, 2025) Dattam, V.K.; Pitchaimani, J.; Doddamani, M.
    Experimental investigation carried out on the thermal deflection behavior of 3D printed poly lactic acid sandwich beams possessing positive, negative, and zero Poisson’s ratio cellular cores is presented. Using a fused deposition modelling based 3D printer, sandwich beams were fabricated and investigated for thermal buckling under different heating conditions. Influence of Poisson’s ratio of the core and orientation of the beam on thermal buckling were also studied. It is found that Poisson's ratio of the core influences the thermal deflection of the beams remarkably. The sandwich beam having a vertically oriented core with zero Poisson's ratio exhibited superior buckling resistance compared to the other two cases. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.
