Stability
Failure under Tensile Stress
·In Weibull probability plot (strain ­ failure), the slope of the
linear data line is the Weibull modulus (m).
ITO on different polymer
(Bending test was used.)
(The failure strain is defined
0
as 63% F.P. in this example.)
The narrow distribution (large
m) means that there is a very
weak point (defect).
