项目摘要
Most ferroelectric multifunctional materials are brittle ceramics, which are predominantly applied in actuators and sensors. There, they are supposed to sustain many millions of load cycles without failure and fracture. Models are developed to understand the parameters influencing damage, and finally to optimize actuatoric devices with respect to their lifetime. They enable predictions of both damage processes and functional properties. Based on calculations and computer simulations, mechanisms of damage are investigated and measures are elaborated increasing life time without deteriorating the actuatoric properties.
大多数铁电多功能材料是脆性陶瓷,主要应用于执行器和传感器。在那里,它们应该能够承受数百万次的载荷循环而不会发生故障和断裂。建立模型是为了了解影响损伤的参数,并最终优化执行装置的使用寿命。它们可以预测损伤过程和功能特性。在计算和计算机模拟的基础上,研究了损伤机理,阐述了在不降低作动性能的前提下提高其使用寿命的措施。
