To evaluate the material strength, tests of compression strength were held.
To review the history, theory and current applications of Weibull analyses sufficient to make informed decisions regarding practical use of the analysis in dental material strength testing.
The required material constants representing initial crack properties are derived from material dynamic strength tests.
A method based on equal failure probability is proposed to map the material strength obtained from test specimens to the equivalent strength for MEMS structural design.
This paper is a sequel to our article 'Lower fractiles of material strength from limited test data', Structural Safety, 7 (1990 67 7567–75.
The nominal lateral load-carrying capacities (P np and P nn ) of each specimen based on beam flexural strength were evaluated by using the actual material strength obtained from test results, where P np and P nn are the positive and negative nominal lateral load-carrying capacities, respectively.
Hereafter, in the evaluation of the experimental results in this study, the material strength obtained from the tests is used instead of the specified strength of concrete, steel re-bars, and retrofit materials.
The common industrial approach to satisfy the certification requirements (EASA AMC 20-29) for composite structures, based mainly on the application of high conservative knockdown factors to the material strength properties and/or performing extensive test campaigns, can lead to oversized structures and to an increase in costs and timing.
Experimental studies were performed at several scales, including material characterization, bond strength tests, small-scale prism tests, and full-scale beam tests.
