The 4-day Strain Analysis course provides an introduction to electrical resistance strain gauges and the associated circuits for strain measurement and transducer applications. It covers the installation of foil gauges using cyanoacrylate and epoxy adhesives, inspection of installations, the measurement of strain and load, and the use of rosettes to determine principal values. The course uses lectures, demonstrations and practical tasks to provide participants with a good understanding of electrical resistance strain gauges, the selection and use of gauges and circuits for strain measurement and transducer applications, the positioning of gauges, and the methods used to install and test gauges and circuits. Some previous strain gauge experience is desirable. Hands-on sessions form an important element of the course and it is therefore necessary to restrict the group size to about 10. The course provides an appropriate preparation for certification at Level 3.
Training & Certification Events
The objective of the Level 2 examination is to enable candidates to demonstrate that they use procedures consistent with the Code of Practice, and are able to direct the installation of gauges, choose appropriate gauges, materials and methods, and make measurements using gauges.
The 3-day Stress Analysis course provides instruction on the siting of strain gauges and the choice of gauge systems. It covers strain measurement, the correction of measured data, the determination of stress and yield load, the use of full-bridge circuits, the principal features of common load cells and the refinement of the bridge circuit. The course uses lectures and hands-on experience to provide participants with a deeper understanding of strain measurement, in order to improve the accuracy of data they use in the determination of stress levels and critical loads in structural components, and to appreciate design features incorporated in devices used to measure load. Hands-on sessions form an important element of the course and it is therefore necessary to restrict the group size to about 10. The course provides an appropriate preparation for certification at Level 3.
The objective of the Level 3 examination is to enable candidates to show that they have a broad knowledge of strain measurement methods and component behaviour, can evaluate strain gauge installations made by other personnel, and can make measurements using strain gauges and determine accurate values of stress. The whole examination takes two days, and has three parts: a practical test a written test an interview
