Atomistic and continuum scale models for flexoelectric nanostructures and composites

He, Bo (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2023)

This work explores the phenomenon of flexoelectricity in nanomaterials and nanostructures by molecular dynamics models and continuum models. Flexoelectricity is an electromechanical phenomenon describing the coupling between ...
Characterizing flexoelectricity in composite material using the element-free Galerkin method

He, Bo; Javvaji, Brahmanandam; Zhuang, Xiaoying (Basel : MDPI AG, 2019)

This study employs the Element-Free Galerkin method (EFG) to characterize flexoelectricity in a composite material. The presence of the strain gradient term in the Partial Differential Equations (PDEs) requires C 1 continuity ...
Computational Machine Learning Representation for the Flexoelectricity Effect in Truncated Pyramid Structures

Hamdia, Khader M.; Ghasemi, Hamid; Zhuang, Xiaoying; Alajlan, Naif; Rabczuk, Timon (Henderson : Tech Science Press, 2019)

In this study, machine learning representation is introduced to evaluate the flexoelectricity effect in truncated pyramid nanostructure under compression. A Non-Uniform Rational B-spline (NURBS) based IGA formulation is ...
