1 APPLICATION OF DESIGN OF EXPERIMENTS TO EVALUATION THE PROPAGATION SPEED OF Lcr WAVES Cleudiane Soares Santos, Aliandro Henrique Costa Santos, Paulo Pereira Júnior and Auteliano Antunes dos Santos Júnior 1

2 Objective Study the influence of the variables(temperature, stress applied in the bar and force applied to the probe), involved on performance assessment of the speed of wave propagation critically refracted longitudinal waves (Lcr waves), in a bar structural aluminum 7050, using the Minitab software. 2

3 Introduction Critically refracted longitudinal waves (Lcr) are obtained after theuseofmeanstorefractwavesparalleltothesurface. incident wave L α 1 α = α 1 = 25.7 β T = 30 β L = 90 transmitter Linking bar receiver acrylic aluminium β L L Lcr Wave acrylic shoes β T transverse T wave Schematic drawing of the generation of waves Lcr (acrylic/aluminium) 3

4 Introduction Every experiment involves a series of variables with varying degrees of importance to the process under study. The most efficient way to conduct an experiment using a scientific approach is called statistical design of experiments (DOE). Represents a set of experiments established on scientific and statistical criteria. 4

5 Methodology The approach used in this research was based on DOE techniques. First, we selected the variables that Influence of Lcr wave propagation speed. Next, was realized the experiment as planning matrix and the program developed in LabView software to generate a database, and finally, we used the software Minitab for the analysis of experiments. 1. Selected the variables that Influence of Lcr wave propagation speed 2. Realized the experiment as planning matrix defined 3. Developed program in LabView software to generate a database 4. Used the software Minitab for the analysis of experiments 5

6 Design of Experiments (DOE) Determination of the parameters of the experiment: Controllable factors and their levels. Factors Low (-1) Medium (0) High (+1) A: Temperature (ºC) 20 22,5 25 B: Stress (bar) C: Force (N) 22,5 53,9 115,8 The factors that were not controlled during the experiment were kept constant for the reduction of experimental error. We used the same mark (Panametrics) for ultrasonic transducers usedinthiswork,withthesamefrequencyof5mhz. 6

Traction device 6. Hydraulic cylinders 7. Hydraulic hand pump with digital manometer 8. Aluminium bar 7050 attached with thermocouple 10

11 Planning Matrix The experimental planning for this work was defined as a full factorial design 3 k = 3 3 (k is the number of factors control of the experiment), resulting in 27 trials, so the Planning Matrix has three levels and three factors. Each test was repeated five times (R1 to R5), totaling 135 results. The repetitions enable the use of hypothesis testing in statistical analysis, which is not the case, but also allow us to estimate the dispersion. 11

18 Conclusions The temperature was the variable with the greatest influence on results. It was observed that the lower the temperature, the higher the values for speed, while the higher the temperature, the lower the values for speed. The test created and defined procedure allowed the evaluation of proposals by the analysis influences the behavior of the propagation speed, indicating that the proposed procedure can be used for this type of analysis. 18

19 Future Work Improve the LabView TM program developed to calculate the propagation speed waves and analyzing the results of the propagation speed of the Lcr waves through the test of influence and other variables at different levels for the variables already studied in this work. 19
