Abstract: A new method on experimental strainstress conversion of elasto-plastic rotating disc is described. Its avantage is that there is no need of calculating the secant modulus by using the tensile curve iteratively. Therefore, the calculating work of experimental strain-stress conversion is greatly simplified.

Key words: rotating disc in elasto-plastic state, plastic area, secant modulus, experimental strainstress conversion
