Different interface models for calculating the effective properties in piezoelectric composite materials with imperfect fiber–matrix adhesion

摘要: Abstract Piezoelectric materials are able to produce an electrical response when mechanically stressed (sensors) and inversely high precision motion can be obtained with the application of field (actuators). The macroscopic properties piezoelectric composites depend upon interfacial bonding conditions constituent phases, microstructures composites. In present work, a new imperfect interface model for thin elastic is derived. Square unit cell was used calculate all coefficients material tensor. calculation performed via FE package ABAQUS™. A computational procedure, based on Python language, developed systematically RVE effective coefficients. Comparisons classical Hashin’s Nairn’s show very accurate agreement debonding perfect boding interface.
