Abstract null null Piezoelectric energy harvesting has attracted tremendous interest for designing sustainable self-powered devices/systems targeted to special environment such as wireless or wearable applications. The traditional cavity (e.g., phononic cavity mode) excitation is highly applicable in terms of sufficient power generation, nevertheless, has to endure the drawback of extremely poor robustness intrinsic to the trivial cavity modes. We propose to use phononic thin plate systems for r...

Abstract null null In this paper, a phase field model is developed and applied to the simulation of quasi-static and dynamic fracture using the nonlocal operator method (NOM). The phase field’s nonlocal weak and associated strong forms are derived by a variational principle. The NOM requires only the definition of the energy. Its differential operators replace the shape functions in methods such as FEM which drastically simplifies the implementation. We present both a nonlocal implicit phase fie...

Abstract null null Experimental realization of single-layer MoSi2N4 is among the latest groundbreaking advances in the field of two-dimensional (2D) materials. Inspired by this accomplishment, herein we conduct first-principles calculations to explore the stability of MC2N4 (M = Cr, Mo, W, V, Nb, Ta, Ti, Zr, Hf) monolayers. Acquired results confirm the desirable thermal, dynamical, and mechanical stability of MC2N4 (M = Cr, Mo, W, V) nanosheets. Interestingly, CrC2N4, MoC2N4, and WC2N4 monolayer...

Abstract null null In this work, we present a nonlocal operator method (NOM) for null dynamic fracture null null exploiting an explicit phase field model. The nonlocal strong forms of the phase field and the associated mechanical model are derived as integral forms by variational principle. The equations are decoupled and solved in time by an explicit scheme employing the Verlet-velocity algorithm for the mechanical field and an adaptive sub-step scheme for the phase field model. The sub-step sc...

The derivation of nonlocal strong forms for many physical problems remains cumbersome in traditional methods. In this paper, we apply the variational principle/weighted residual method based on nonlocal operator method for the derivation of nonlocal forms for elasticity, thin plate, gradient elasticity, electro-magneto-elasticity and phase-field fracture method. The nonlocal governing equations are expressed as an integral form on support and dual-support. The first example shows that the nonloc...

Abstract null null The investigation of electromechanical properties for the newly added two-dimensional materials is challenging and enthralling. In this work, we consider studying the piezoelectric and flexoelectric properties of diamane monolayers, firstly proposed by density functional simulations and later synthesized in experiments. For this aim, we develop machine learning-based inter-atomic moment-tensor potentials along with the charge-dipole model to calculate the electrical polarizati...

We present a methodology to perform inverse analysis on reconfigurable topological insulators for flexural waves in plate-like structures. First the unit cell topology of a phononic plate is designed, which offers two-fold degeneracy in the band structure by topology optimization. In the second step, piezoelectric patches bonded over the substrate plate are connected to an external circuit and used appropriately to break space inversion symmetry. The space inversion symmetry breaking opens a top...
