Grid Analysis
This week we examined the strain on the fractured DP-980 samples with a Grid Analyzer. Seen in the image to the left, this instrument locates the grid squares on each sample and calculates the major and minor strains of that particular square. To properly analyze each specimen, we analyzed the grid squares near the area of fracture as well as outside the necking region. This allows for measurement of localized and global strain. Pictured below is the specimen with the etched grid.
