SERIER, M.; BENAMARA, N.; MEGUENI, A.  e  REFASSI, K.. Modeling of Cracked Beams by the Experimental Design Method. Lat. Am. j. solids struct. [online]. 2015, vol.12, n.9, pp.1641-1652. ISSN 1679-7825.  http://dx.doi.org/10.1590/1679-78251403.

The understanding of phenomena, no matter their nature is based on the experimental results found. In the most cases, this requires an important number of tests in order to put a reliable and useful observation served into solving the technical problems subsequently. This paper is based on independent and variables combination resulting from experimentation in a mathematical formulation. Indeed, mathematical modeling gives us the advantage to optimize and predict the right choices without passing each case by the experiment. In this work we plan to apply the experimental design method on the experimental results found by (Deokar, A, 2011), concerning the effect of the size and position of a crack on the measured frequency of a beam console, and validating the mathematical model to predict other frequencies
