Designing Microstructures/Structures for Desired Functional Material and Local Fields
Abstract
The investigations have focused on the predictive modeling and optimal design of multifunctional materials/structures as proposed. Along the line of predictive modeling, the PI, supported students and collaborators have (i) established an atomistic model for surface elasticity, (ii) derived a new type of Maxwell stress in soft materials due to quantum mechanical-elasticity coupling and elucidated its ramification in engineering multifunctional soft materials, and (iii) demonstrated the possibility of concurrent magnetoelectricity and piezoelectricity in soft materials. Concerning local field in heterogeneous structures, we have shown designs of thermoelectric composites and the feasibility of large-scale power plants based on thermoelectric effects. we achieve designs of structures that can amplify static electric/magnetic fields or temperature gradient. These designs can be used to improve sensitivity of telecommunication receivers and efficiency of heat engines / thermoelectric generators. We also show optimal geometries of minimum field concentration that may be used to mitigate fatigue damage and improve reliability and life-span of structures.
