In this study, we obtained and characterized a piezoelectric composite with 1-3 connectivity from castor oil polyurethane (PUR) and lead zirconate titanate (PZT) rods. Two samples were obtained, one with 15% PZT volume and ...

A piezoelectric composite homogenization model (PCHM) is presented in this article. A systematic method for predicting the composite macroscopic history-dependent electromechanical response is developed and particularized ...
