Monitoring of damage degradation in materials is vital as any cracks will reduce local stiffness, accelerating the ageing process of the physical assets. In-situ ultrasonic monitoring data is valuable for giving the inspectors information on the level of what may be wrong with the structural systems. However, purely data-driven representations do not always give inspectors enough information and the ability to predict how the system will behave in the future. This can be achieved by utilising some knowledge of the physics that underpins the system. This project will use the fusion of experimental data and physical models for failure prediction of materials, by taking measurements and developing models that are hybrid in nature.

监测材料的损坏退化至关重要，因为任何裂缝都会降低局部刚度，加速物理资产的老化过程。现场超声波监测数据对于向视察员提供关于结构系统可能出现的问题程度的信息很有价值。然而，纯粹的数据驱动表示并不总是为检查员提供足够的信息和预测系统未来行为的能力。这可以通过利用支撑系统的物理学知识来实现。该项目将通过测量和开发混合性质的模型，将实验数据和物理模型融合在一起，用于材料的失效预测。
