19	Objective of the Course:	Experimental stress analysis has an important place for many engineering branches, especially mechanical engineering, as it includes techniques that engineers can use to estimate the stress and strain distributions that will occur in materials due to different loading conditions. The stability and strength conditions of structural elements and machine parts under the effect of load can be evaluated in a healthy way by using these techniques. Thus, experimental stress analysis is the most important tool used in the design and analysis of machines and structures. The aim of the Stress Measurement Techniques course, which is an introduction to experimental stress analysis, is to help students consolidate the stress, strain and damage concepts they have learned in the strength course, understand experimental stress analysis techniques and improve their ability to apply them in real engineering designs. At the end of this course, students will learn what experimental stress analysis is and why it is necessary, the common experimental stress analysis techniques such as Moire, Optical Sensor, Photoelasticity and surface coating techniques, and the electrical strain gauge techniques and the measuring devices used will be learned in detail. . Therefore, the experiments to be done by the student have an important place in the teaching and understanding of this course. The students who take the course will develop experiments for the load cases including tensile, compression, bending, torsion and their combination, which they learned theoretically in the strength course, will make real measurements with measurement elements such as strainage, lvdt, encoder, load cell, and will compare the results with theoretical results. Contribution will also be provided for students to develop their ability to take part in teamwork and lead when necessary, to prepare a written report and to present the results of the analysis verbally. In addition, they will make a literature search and learn about the new stress measurement techniques that have emerged as a result of the rapid developments in experimental stress analysis.
