When flaws are consistent and evenly distributed, samples will behave more uniformly than when flaws are clustered inconsistently. Significance: This study confirmed the efficacy of the Rocatec system for bonding composite resin to metal or ceramic substrates. Bernhart, M.M. This must be taken into account when describing the strength of the material, so strength is best represented as a distribution of values rather than as one specific value. This results in a clear connection between the probability of breakage and the load on the workpiece. m is called the Weibull modulus: lower m means a greater variation in strength. The flexural strength values were found to range from 266.7 to 357.5 MPa. xref # K.12fdsM +3D0dmp(sb !FTNF()( The theory is based on the concept of the weakest link.
