This study focuses on Deformation mechanism numerical and experimental investigation of the mechanical behavior of 3D periodic single-material cellular D- 3D-printed multimaterial composites structure and the corresponding co-continuous composite. Diﬀerent volume fractions of desired geometry were Compliancy fabricated by multimaterial fused deposition modeling (FDM) technology and compressive mechanical prop- Strain recovery erties of the samples were obtained by mechanical tests. It was observed that embedding a hyperelastic material Load-bearing capacity to the cellular structure dramatically hindered the shearing bands in localized regions to develop, thereby made Instability it feasible for composite material to undergo larger deformations without failure. Furthermore, it was demon- strated that the soft phase in
