In a mathematical analysis of piezoelectric models, we use the terms "the electrically open and short circuit case" for which we have some mathematical definition as well.
What is the physical significance of these boundary conditions in making sensors and other devices?
Hi Sonal Nirwal ,
For me, as FEM user, the main physical significance of these terms lies in definition of piezomechanical constants. When obtaining these constants, "short cirquit" is equivalent to zero electrical potential gradient, while "open cirquit" is equivalent to zero electrical displacement in piezomaterial.
Hi Sonal Nirwal,
The surface is metallized (short circuit (CC)): corresponds to the vanish of the electric potential.
The surface is non-metallized (open circuit (CO)): corresponds to the vanish of the surface charge density.
