As a simple and highly accurate axial force management method during manufacturing maintenance of bolt-tightened structures, we examined to calculate the from images bolt head. In this method, is calculated using strain on head measured by digital image correlation (DIC) technique relationship between finite element analysis (FEA). We through two comparisons. The first was compare DIC with gaug...

Convolutional Neural Networks (CNNs) constitute a class of Deep Learning models which have been used in the recent past to resolve many problems computer vision, particular optical flow estimation. Measuring displacement and strain fields can be regarded as case this problem. However, it seems that CNNs never so far perform such measurements. This work is aimed at implementing CNN able retrieve...
