Rational design of piezoelectric metamaterials with tailored electro-momentum coupling
Zhizhou Zhang, Jeong-Ho Lee, Grace X. Gu
Piezoelectric materials have wide sensing and energy transduction applications due to their inherent coupling of mechanical deformation and electric field. Recent discoveries have…
Efficient snap-through of spherical caps by applying a localized curvature stimulus
Lucia Stein-Montalvo, Jeong-Ho Lee, Yi Yang +3
In bistable actuators and other engineered devices, a homogeneous stimulus (e.g. mechanical, chemical, thermal, or magnetic) is often applied to an entire shell to initiate a snap-…
The nonlinear buckling behavior of a complete spherical shell under uniform external pressure and homogenous natural curvature
Douglas P. Holmes, Jeong-Ho Lee, Harold S. Park +1
In this work, we consider the stability of a spherical shell under combined loading from a uniform external pressure and a homogenous natural curvature. Non-mechanical stimuli, suc…
Theoretical Modeling of ME effect at Low frequency and Resonance Frequency for Magnetoelectric Laminates with Anisotropic Piezoelectric Properties
Deepak Rajaram Patil, Yisheng Chai, Rahul C. Kambale +11
A new theory is developed for the magnetoelectric (ME) coupling in a symmetric 2-2 ME laminate having a representative piezoelectric crystal (PMN-PT) particularly with anisotropic…
