摘要:

In the derivation of the classic Weibull strength distribution for brittle solids, it is assumed that the number of flaws is large. When small specimens are tested the number of flaws may not be large and the number in any one specimen may be significantly different to the expected number. In this case the effective Weibull modulus will be less than that measured from tests on large specimens.
