| Outline of Final Research Achievements |
This study was aimed to develop a control technique of cracking pattern formation for mesh-like cracks in shrinkage deformation and the expansion deformation. Therefore, this study was to investigate the technique of the network model analysis of the elastic spring element. In the analysis, extracts a portion of the resilient spring elements by a random number, an elastic modulus is set to 0, representing the non-uniformity of the material. As a result, in each of shrinkage deformation and expansion deformation, it was possible to express the pattern formation of the reticulated cracks.
