Abstract
Recently, the accidents in industrial infrastructures due to deterioration or lack of maintenance became a serious problem. Therefore, the appropriate maintenance methods, that extend its life span and reduce its repair cost, have been examined. This paper proposes the new maintenance method based on a novel mechanoluminescence sensor. The mechanoluminescence sensor is made of ceramic powders, and it emits according to the strain. This characteristic can be expected to visualize strain distribution on the structures directly, which this sensor is applied to. In this paper, we discussed the modeling method of the mechanoluminescence using neural network in oredr to use the sensor as the strain monitoring tool.
