However, the computational time associated with this method increases as the fidelity of the material representation improves, limiting its practical implementation in commercial finite element software for large-scale structural calculations in which a Representative Volume Element must be considered at each integration point. To overcome this limitation without sacrificing precision or efficiency, machine learning can be employed to develop a digital twin of the homogenization-based constitutive law.

Mechanical models are developed to assess the influence of geometrical parameters on the mechanical responses of BAB, which are validated through both numerical simulation and experimental results. By assembling these proposed BABs, we demonstrate that 3D mechanical metamaterials with multistable auxetic behavior can be designed and fabricated. Our results show that these metamaterials exhibit sequential deformation under applied loading and possess programmable mechanical properties.

To model these phenomena, an analytical framework is developed to describe stress evolution in cylindrical fibers. The elastic-creep behavior of the oxide is represented by a viscoelastic Maxwell model. By solving the governing ordinary differential equations (ODEs) and applying material properties relevant to the oxidation of SiC fibers, the study provides insights into the interplay between oxide growth, stress relaxation, and fiber geometry.

This study employs a modified Mori-Tanaka (MMT) model to predict the effective thermomechanical behavior of SMPs. By utilizing a homogenization procedure, a constitutive equation describing the evolution of the effective behavior of SMPs under thermomechanical loading was proposed. The model accounted for the SMP's dual-phase structure, consisting of active and frozen phases, and determined the effective stiffness by considering each phase's shape and volume fraction. Unlike existing phase transition models, the proposed model incorporates the interaction between phases and the phase transition process throughout the thermomechanical cycle. The model was implemented in the UMAT user subroutine of the ABAQUS software to simulate the mechanical behavior of SMPs. Investigations into various inclusion phase shapes revealed that an ellipsoidal shape most accurately represents the morphology of the inclusion phase. While shape recovery is influenced by inelastic strain, the stress response of the present model showed improved agreement with experimental results due to the consideration of phase interactions during transformation. Application of the proposed model to the auxetic behavior of a re-entrant structure fabricated from PLA demonstrated that varying Poisson's ratios and cell-opening factors (CoF) can be achieved by programming different deformation magnitudes. The most negative Poisson's ratio (−0.64) was obtained at a 70° re-entrant angle induced by a 20 mm pre-displacement.
