Figure Lengend Snippet: The Weibull modulus (m) was the upward gradient of the line. The characteristic strength (σ 0 ) was the strength at a failure probability of approximately 63.2%.

Article Snippet: Additionally, a two-parameter Weibull cumulative distribution was conducted on the flexural strength and impact strength (Origin(Pro), Version 2024; OriginLab Corporation, Northampton, MA, USA.) to calculate the Weibull modulus and Scale parameter.

Figure Lengend Snippet: Mean bond strength values (MPa ± standard deviations) of all 4 test methods (SBT; TBT; µSBT; µTBT), distribution, and frequency of failure types, Weibull modulus. Failure types were classified as follows: Score 1: cohesive1: cohesive failure in the substrate; Score 2: mixed1: a combination of adhesive and cohesive failure types in the substrate and bonding agent; Score 3: adhesive: adhesive failure of bonding agent from the resin composite surface with no remnants on the resin composite; Score 4: mixed2: a combination of adhesive and cohesive failure types in the bonding agent and resin composite; Score 5: cohesive2: cohesive failure in the resin composite. The same superscript lowercase letters in the same column indicate no significant differences based on the substrate type, and uppercase letters are based on the test method ( p < 0.05). Test group descriptions are explained in Figure 1 . Significantly different bond strengths in comp-comp substrates are marked with the superscripts a, b, c, while significantly different values for Ceramic-comp substrates were distinguished using the superscripts A, B, C and D.

Article Snippet: Two-parameter Weibull distribution (Minitab Software V.16, State College, PA, USA) was used to evaluate reliability and predictability of the adhesion, while two-sided chi-square testing was used for failure type analysis.
