Thermodynamic consistency is ensured by embedding nonlocal effects into the inertial terms of the field equations through a regularization kernel that accurately captures dispersive behavior in all propagation directions, thus overcoming the intrinsic limitations of classical continualization methods. The integral-form continuum model, spectrally equivalent to the discrete one at the band-structure level, is simplified via Taylor expansions of the kernel, leading to systematic higher-order gradient models.

Quasi-static axial compression tests and validated finite element simulations were performed to investigate the crushing behavior and energy absorption characteristics. For benchmarking, the antiprism tubes were directly compared with square origami tubes of identical mass and wall thickness. The antiprism design introduces a distinct folding mechanism that generates multiple interacting fixed and traveling plastic hinges, leading to markedly improved energy absorption. Short antiprism tubes (<em>M</em> = 1, <em>N</em> = 3) achieved 54% higher average specific energy absorption (SEA) and 63% greater crushing force efficiency (CFE) compared to square origami tubes.

To address this limitation, we develop a semi-analytical heterogeneous bistable chain model composed of dissimilar bistable elements. Each element is described by trilinear force-displacement relation with distinct phase transition thresholds. The two limiting pathways, the minimum energy (thermodynamic equilibrium) and maximum hysteresis (athermal) paths, are generalized to account for heterogeneity.

Furthermore, through heterogeneous bistable chain model, we analytically reveal the mechanism of coupled phase transitions: a cooperative phenomenon unique to heterogeneous multistable systems where the phase transition of one element can induce phase transitions in others. The predictive capability of the proposed framework is validated through the design of gradient multistable metamaterials, where theoretical predictions show excellent agreement with finite element simulations and experimental measurements.

Among various approaches, extracting electrical energy from ocean waves through piezoelectric mechanisms offers an innovative and eco-friendly solution. Acting as flexible plate-type wave energy converters, these structures are designed to efficiently capture the hydrodynamic energy of surface waves. The primary motivation behind this work arises from the observation that surface-piercing, vertically oriented piezoelectric plate-type wave energy converters have not been reported in the existing literature, to the best of the authors’ knowledge. Despite their significant potential for practical marine energy applications, vertical piezoelectric configurations can provide advantages in achieving the optimum electrical load resistance, thereby maximizing harvested power, compared to horizontally oriented configurations (Kazemi et al., 2021). To overcome the mathematical complexities associated with the coupling between structural flexibility and piezoelectric interactions, a rigorous semi-analytical framework is developed. These complexities arise due to boundary conditions that involve higher-order derivatives with complex-valued coefficients. The governing problem is reformulated into a set of coupled integral equations by employing Green’s function solutions along with mixed Fourier transform techniques. These equations are subsequently solved through a Singularity-Respecting Galerkin approximation, yielding accurate evaluations of the hydrodynamic response, including the reflection characteristics, wave power absorption efficiency and hydrodynamic wave forces. Furthermore, a comprehensive parametric investigation is undertaken to elucidate the influences of wave and structural parameters on plate deflection, bending moments and shear forces. Deploying multiple piezoelectric plates in an array has been found to be a more promising approach for wave power absorption. Widening the spacing between adjacent plates greatly influences the deflection of the leeward plate, regardless of whether the edges are clamped–clamped or clamped–free.

The constitutive equations are derived from a constrained minimization of a dual dissipative potential, with positive plastic dissipation imposed to ensure thermodynamic consistency. The plastic slip gradient is decomposed into recoverable and unrecoverable components, rather than decomposing the higher-order stresses. The constrained minimization results in the higher-order stress of each slip plane evolving nonlinearly, similar to the Armstrong-Frederick type backstress model. The evolution equation includes strain gradient hardening along with a relaxation term. In the absence of the relaxation term, the formulation produces purely gradient-induced linear kinematic hardening without additional plastic dissipation. The inclusion of the relaxation term enhances dissipation and gives rise to an higher-order isotropic-type hardening effect associated with the plastic slip gradient. As cumulative plastic flow progresses due to evolution, the higher-order stress attains saturation. Both size-dependent kinematic and isotropic hardening also reach saturation when the recoverable part of the slip gradient saturates. Conversely, the unrecoverable slip gradient continues to rise with the plastic flow. Numerical simulations are performed to assess the effect of the relaxation coefficient on a single-crystal infinite shear layer subjected to monotonic, cyclic, and non-proportional loading conditions, with responses compared to the dislocation dynamic study. Two-dimensional polycrystalline tension with a hard interface illustrates the effect of grain size on macroscopic yield stress.

In this paper, we extend these models to non-isothermal processes in one spatial dimension in the absence of heat flux. By coupling the balance laws of momentum and energy with a balance law for an additional nonequilibrium stress variable and enforcing the entropy principle together with convexity, we derive a thermodynamically admissible system of nonlinear evolution equations. The resulting model is symmetric hyperbolic, which guarantees local well-posedness of the Cauchy problem and admits weak solutions, including shocks. For Newtonian production terms, we further verify the Shizuta–Kawashima condition, yielding global-in-time smooth solutions for sufficiently small initial data. A unified framework is thus obtained, capable of describing either nonlinear thermo-viscoelastic behavior or temperature-dependent non-Newtonian rheology in the parabolic (zero-relaxation) limit.

The chain structure operates as a generalizable mechanical principle by transforming tensile loads into confined axial compression within an internal energy-absorbing core, thereby suppressing the development of tensile strain in non-loading directions. This boundary confinement strategy effectively delayed global failure and enhanced energy absorption through controlled damage progression and stress redistribution. Quasi-static compression tests on various ceramic lattices revealed distinct deformation modes and failure mechanisms under unconstrained loading. Furthermore, quasi-static and dynamic tensile experiments on chain structure filled with lattices provided insights into constrained failure behavior and energy absorption characteristics under constrained loading. The results demonstrate that ceramic lattices within chain structure can absorb kinetic energy even after brittle fractures occur. Compared to unconstrained situations, the effective displacement of lattices under constraint can be increased by at least 19 times and the specific energy absorption can be increased by over 17 times. Notably, the BCC lattice-based chain absorber exhibits a stress plateau and large effective displacement, highlighting its ability to delay failure through progressive densification.
