Structural health monitoring (SHM) refers to the process of implementing a damage detection and characterization strategy for engineering structures. There are many SHM technologies available and works on different fundamental physics principle. With a continuing drive increase the speed of inspection, to reduce the preparation required and, if possible, to inspect without the need to shut down operation, many highly sophisticated robots and automated systems have been employed. Acoustic Emission testing and Vibration testing are examples of dynamic monitoring technologies for online SHM strategies that are capable for locating crack propagation in any in-service structures. (a) (b) (c) (d) Analyse ONE (1) similarity in the construction of the sensors for both Acoustic Emission testing and Vibration testing. Use sketch or illustration to support your evaluation. (3 marks) Discuss TWO (2) differences in the sensor construction for both Acoustic Emission testing and Vibration testing. (6 marks) A pressure vessel with very small lack of fusion inside the metal weldment is used to contain processed crude oils. Preliminary quality control fails to detect the voids and approve the pressure vessel to operate. During in-service operation, the pressure vessel subjected to dynamic loading. Based on your answer in Q2(a) and Q2(b), analyse the pressure vessel integrity during the in- service operation and suggest the MOST suitable dynamic monitoring method to be employed on the pressure vessel. Justify your suggestion on the source of dynamic input for the dynamic sensor as per your suggestion. State any assumptions you have made.. Re-evaluate your answer in Q2(c) when the pandemic likes Covid-19 strikes the country and all the workforces in the industries are on restricted movement order. Would the SHM strategy for the pressure vessel is sufficient to monitor the structural health of the pressure vessel? Evaluate the situation and explain using the type of signal that can be captured using the suggested method, and the sufficiency of the sensor to monitor the structural integrity during the pandemic. If your answer is similar with Q2(c), elaborate on how the structural integrity of the structure can be determined remotely. If your answer in not similar with Q2(c), justify why and suggest a new method?
