摘要: The deformation behavior of materials consists observing the dimensional changes as a result applied forces. These are directly related to quantities called strains, and forces stresses. This paper describes new method for determining strain distribution resulting from complex stress applications. measurements involve evaluation grain boundary shape seen on plane polish before after deformation. In particular, variation in across walls hollow drawn metal tubes is measured illustrate application method. measurement based an analysis Philofsky Hilliard (1967) which determines orientation traces boundaries polish. described another by (1967).
