Abstract: Strain measurement is a very important procedure in mechanical engineering. It has been the subject of the research in theoretical and experimental work. Wheatstone bridge or resistance strain measurement is the most widely used method in experimental stress analysis. Using the advanced virtual instrument technology, there is a possibility to solve the problems of traditional resistance strain instruments. In this paper we give an overview of strain measurement and then introduce the concept and characteristics of virtual instruments applied for that purpose.
Key words: strain measurements, Wheatstone bridge, virtual instrument, LabVIEW, students’ education.
