研究目的
The main objective of the present study is to show the e?ects of layer thicknesses, material properties and applied loads on the fracture properties of a PE-PM-PE sandwich structure subjected to in-plane electromechanical loads.
研究成果
The conclusions of the present paper may be useful for the design and fracture prediction of layered piezoelectric-piezomagnetic structures. The study shows the effects of material properties, structure geometries, electromechanical loads, and crack location on the stress intensity factors.
研究不足
The study is limited to plane strain problems and does not consider three-dimensional effects or dynamic loading conditions.
