Notes:
Experimental characteristics of complementary plastic energy produced by a stress-strainhysteresis curve at a saturated stage in low cycle fatigue are investigated for some steels, and mechanicalmodels for analyzing microstructures of fatigued metals are discussed. As a result, it isfound that volume of a cell is varied in inverse proportion to plastic strain range: the density of cellsis in proportion to plastic strain range. Consequently, the total number of cells is proportional toplastic strain range. This final conclusion is similar to Winter's opinion concerning persistent slipband structures in high cycle fatigue [1] where, although wall spacing of a cell is invariable andinde-pendent of plastic strain range, a region occupied by persistent slip bands increasesproportionally to plastic strain range and consequently the number of cells is in proportion to plasticstrain range
