This study models piezoceramic hysteresis using circular distributions to link microscopic domain behavior to macroscopic properties. This approach simplifies analysis and accurately characterizes material hysteresis loops.

Area of Science:

  • Materials Science
  • Solid Mechanics
  • Physics

Background:

  • Piezoceramic materials exhibit complex hysteresis behavior.
  • Modeling this behavior is crucial for device applications.
  • Existing models often lack a direct link between microstructural domain dynamics and macroscale properties.

Purpose of the Study:

  • To develop a model for piezoceramic hysteresis based on circular distribution functions.
  • To bridge microscopic domain orientations with macroscopic material behavior.
  • To provide a computationally efficient method for characterizing hysteresis.

Main Methods:

  • Utilizing circular distribution functions, specifically the von Mises-Fisher distribution for 2D models.
  • Defining internal state variables based on domain orientation distribution parameters.
