Processing of Large Amount of Experimental Data Collected During Laboratory ProceduresAbstractProcessing of the large experimental data files collected during laboratory procedures innondestructive evaluation (NDE) course is described in this paper. In this course, students learnthe physical principles and fundamentals of ultrasound material characterization. Students alsolearn industrial applications of NDE techniques and procedures and become familiar withdetection and characterization of defects in materials, such as flaws and cracks. During theexperiments, students collect extensive amount of data using special UTWin software. Later,these data files are processed using Excel to evaluate ultrasound parameters of various materials,such as sound velocity, attenuation coefficients, and properties of piezoelectric transducers. Theresults of the experiments and conclusions are presented by the students in comprehensivelaboratory reports. The process of comparing all individual files to calculate required parametersis very time consuming. This task can be simplified and automated using macros. The specialExcel macros were developed to assist the students with processing of the large data files.Evaluation of the collected data, the description of the final results, and data analysis arepresented using figures, graphs, tables or other convenient forms.
