Abstract
I have found a convenient method for the measuring of the elasticity-degree of testing pieces, by which the elasticity-degree may be very easily and simply known without the stress-strain curve or the hysterisis curve.
Now could this method be scientifically true ?
According to my trial of the theoretical confirmation for this, the relation between the elasticity-degree (Young's modulus) and the ratio of the breaking-stress to the breaking-strain is to be established as follows:
Y=S(1+c)/(1-c)
where Y: Young's modulus
S: the ratio of the breakings-tress to the breaking-strain
c: constant (0_??_c<1)
