... designs with different geometries. The model predictions are thoroughly verified by mechanical experiments on three-dimensional (3D) printed specimens and finite element simulations with periodic boundary conditions. The new integrated monoclinic-micropolar model can predict the anisotropic elastic...

... artifacts in dielectrics. In this article, we show that the reverse is also possible and potentially advantageous in certain situations (such as energy harvesting). By constructing a computational homogenization approach predicated on the finite element method, we argue that composites made of piezoelectric...

.... A unified V-beam finite element was developed to reduce the nodal degrees of freedoms of the RVE to enable closed-form analytical solutions. The elasticity constants were derived as functions of the angle of the V-shaped wings, nondimensional in-plane thickness of the ribs, and the stiffness...
