Polish Academy of Sciences (Poland)
What is the innovation and what is it about?
Three years of cooperative research between Prof. W. Ostachowicz’s group at Polish Academy of Sciences and Prof. M.S. Cao’s group at Hohai University, supported by the programme FP7-PEOPLE-2009-IAPP (Grant Agreement Number 251309), focuses on the development of new methods and technologies for structural health monitoring relying on multiscale dynamics theory. Generally, the innovations improve not only the state of the art but also the state of use of multiscale dynamics theory in damage identification, noise suppression and dynamic property characterization. Specifically, the main novelties of innovations are threefold: (i) formulation of multiscale dynamics concepts, e.g., multiscale shear strain, for creating new principles of structural health monitoring; (ii) establishment of laser scanning-aided multiscale technologies, e.g., multiscale modal curvature, for revealing damage in noisy conditions; (iii) integration of principles, methods and technologies into structural health monitoring systems. These innovations are accomplished by close cooperation in various research components, largely by working together.
What are the key impacts?
The innovation has positive impacts on the competitiveness of Chinese and Polish structural health monitoring technology. The key impacts are threefold: (i) the innovation launches a scientific branch of multiscale dynamics-based structural damage identification; (ii) the innovation generates sophisticated structural health monitoring technologies that can reduce maintenance costs and improve safety of structures; and (iii) the innovation holds promise of establishing an upgraded industrial process, namely health monitoring-based proactive maintenance of structures. Furthermore, our cooperation has set in place a “visible practice” that can stimulate the participation of European/Chinese researchers in China/EU-funded initiatives, thereby reinforcing future science and technology cooperation.
What are the added values and what were the biggest challenges of your cooperation?
Prof. W. Ostachowicz’s group and Prof. M.S. Cao’s group have created a sustaining cooperative mechanism to produce innovative technologies for structural health monitoring. The cooperation features consolidated competitiveness arising from joint intellects, complementary resources, and mixed cultures. The cooperative team evokes best capacities and influences of each group and each individual for the innovations of the whole, while the good influences of the whole aid each group and individual. These innovations cannot be achieved by any one side. At present, the biggest challenge for the cooperation is to create a joint research base to promote and expand the cooperative outcomes.
