Surface effects in multi-functional nanomaterials

Program: VEGA
Reduction of the size of structural elements to the order of its material microstructure yields arising exceptional properties due to the engagement of physical processes not occurring at macroscopic structures. In contrast to macro-sized structures, the surface effect should be considered due to large ratio of surfaces to volume in nano-sized structures. The flexoelectric and flexomagnetic effects are electromechanical or magnetomechanical coupling phenomena widely existing in many advanced materials with large strain gradients (nano-sized structures), and may significantly affect the multiple physics coupling behaviors of them. The main objective of this project is to fully understand the mechanisms for multiple physics field coupling in smart materials involving the surface effects in flexoelectric and flexomagnetic materials, and provide general ideas for the optimal design of advanced composite materials.

Multiphysical effects in micro/nano structural elements in MEMS/NEMS devices

Program: VEGA
The global aim of this project is to give a unified theoretical and numerical treatment of the micro/nano plateand/or beam bending in interactions with various physical fields. Besides the classical theory of plates/beams(CLT), we shall consider also the first and third order shear deformation theories (FSDT and TSDT). Moreover,we allow the materials of the plates to be functionally graded (FGM) both in transversal and in-plane directions,hence the governing equations are partial differential equations with variable coefficients. We intend to developadvanced numerical techniques, like the Moving Finite Element Method (MFEM) to solve the rather complexboundary value problems. The numerical simulation of the effects of functional dependence of materialcoefficients in multifield coupling and analyse the size-dependent effects can lead to deeper understanding ofphysical processes in response of micro/nano structural plate/beamlike elements.
