Outline of Final Research Achievements

With the aim of application in the field, in the present research, some problems of the previously developed strain visualization sheet were solved, the materials and structure of the device were improved in order to achieve higher accuracy and simplify the installation method, and the performance of the improved device was verified. As a result, it is possible to obtain strain values with resolution of <100μεby visual observation and accuracy of approximately 10 με by image processing. The temperature characteristics of the strain visualization sheet were also clarified, and simplification of the installation method was possible. Thus, this study confirmed the applicability of the strain visualization sheet for use in the field.
