Paper Abstract

For analysis of two dimensional plastic deformation of coarse crystal aluminum sheet specimen under several forces, a new microcomputer-aided analytic method to monochromatic video images of plastic deformation of fine square grids which have excellent contrast to the specimen and good deformability with the specimen was developed. Images on the specimen in testing are taken continuously with a CCTV camera having an object lens with suitable magnification and recorded into a video tape as usual. Selected images are converted into digital data and written into a floppy disk one and after another, and an image made by binary data is transfered monochromatically on a colored, high discrimination display of a micro-computer, and Cartesian coordinates of each cross point after a new fining processing are read out, several deformation distribution map and strain map in various cases shown by vectorial expression is gotten on a display and a printer also. The analytic process, an experimental instance and some points at issue are reported here.
