Electromechanical modeling is becoming an essential tool to model modern devices particularly when the strain engineering is used to tune the electrical and optical properties of materials. Furthermore, an emergent class of devices, such as piezoelectric nanogenerators, are designed to convert the elastic energy into electricity. Elasticity brings features developed for continuous elasticity into device modeling. The coupled treatment of the electro-mechanical problem within a unique framework allows to explore the feasibility of devices where the mechanical deformation plays a fundamental role. Elasticity includes isotropic as well as anisotropic stiffness tensor to model the elastic properties of materials.
One of the main features of Elasticity is the possibility to calculate the strain induced by the lattice mismatch.
