CHAPTER 7 DISLOCATIONS AND STRENGTHENING …
www3.nd.eduGrain boundaries are barriers to slip: Owing to misalignment of the slip planes in adjacent grains, a dislocation passing the grain boundary have to change its direction and thus lose its energy. A single grain may be favorably oriented for slip, but cannot deform until the adjacent grains (less favorable) are also capable to slip;

CHAPTER 5 SOIL CLASSIFICATION AND LABORATORY TESTING
secure.in.gov5.3.1 GRAIN SIZE DISTRIBUTION The results of sieve analyses, plotted in the form of a gradation curve, are used to estimate soil permeability. The following tests shall be performed on samples obtained to verify the field classification of the major soil types encountered during the investigation. The number of tests
