Structural health monitoring stresses

The safety of ship lock is related to the people s life and property in the downstream, so that the ship lock structure health monitoring is a critical issue to avoid its damages. The stress state of ship lock structure is dependent on its type and structural complexity. In addition, the temperature and construction methods have a great influence on the structural quality. Thus, strengthening the structural temperature and stress-strain monitoring during the construction plays a significant role to ensure the construction quality of the ship lock. 

The development of multi-functional textiles for appUcation in the construction sector to increase ductility and structural strength of masonry structures, to monitor stresses, deformations, acceleration, water level variation, and pore pressure, to detect the presence of fluids and chemicals, and to measure structural health through the innovative developed solutions. 

The recent trend is to develop low-cost techniques to assess the quality and structural health of composite structures in a vehicle, starting from the fabrication of the composite structure to actual service in the field. While NDE techniques are not yet ideal for online monitoring of structural health, investigating the stress-strain history from locally stored data prior to failure can help in understanding the causes of the irreversible damage (Wang and Chung, 2006). 

The elastico ML of nanoparticles has potential for many sensing and imaging devices such as stress sensor, visualization of stress distributions in solids, visualization of stress distribution near the tip of crack, visualization of quasidynamic crack propagation in solids, visualization of defects in pipes, light sources, mechanical evaluation of orthopaedic devices like artificial legs, ML-based health monitoring system of structures, etc. 

In conclusion, fibre optic sensors are ideal eandidates to be embedded in textile structural composites for monitoring manufaeturing processes and internal health eonditions. The sensors provide an effective means by whieh the distributions of a number of physieal parameters, such as temperature, stress/strain, thermal expansion, pressure, ete., ean be quantitatively determined. In integrating the sensors into textile eomposites, apart from the properties of the sensors themselves, the rehabihty of the sensors and sensing seheme as well...
