Abstract Flexoelectricity is a general electromechanical phenomenon where the electric
polarization exhibits a linear dependency to the gradient of mechanical strain and vice versa.
The truncated pyramid compression test is among the most common setups to estimate the
flexoelectric effect. We present a three-dimensional isogeometric formulation of
flexoelectricity with its MATLAB implementation for a truncated pyramid setup. Besides
educational purposes, this paper presents a precise computational model to illustrate how the
localization of strain gradients around pyramidal boundary shapes contributes in generation
of electrical energy. The MATLAB code is supposed to help learners in the Isogeometric
Analysis and Finite Elements Methods… More >
