It is extremely important that the structures that support our lives have the necessary forces to withstand external forces and loads during the period of use. However, we cannot see the force information and whether the mechanical behavior has deteriorated or not. Instead, we predict the strength of the structure based on our experience and knowledge, and feedback to the design. However, some questions shod be remaining. Are the past knowledge and simulation correct? Are there any assumptions? Is there any information that we are not aware of? In response to this issue, we have been visualizing "force information" originating from structural materials and structures by utilizing our originally developed "mechanoluminescence (ML) technology" that can visualize dynamic strain distribution. This section introduces mechanoluminescence technology and its visualization strategy, as well as health monitoring, improvement of design and prediction, and development of standards for the use of visualized information.
