In engineering, stress analysis refers to the uses of the methods to determine the stresses and strains in materials and structures subjected to forces. The [course_title] mainly highlights the fundamental aspects of experimental stress analysis that essentially covers accomplishment of the various techniques, such as photoelasticity, strain gauges, etc.
This course also provides a short presentation on the emerging techniques, including digital image correlation and more. Lastly, you will learn about the theoretical aspects of six different experimental techniques in an energetic form.
Assessment
This course does not involve any written exams. Students need to answer 5 assignment questions to complete the course, the answers will be in the form of written work in pdf or word. Students can write the answers in their own time. Each answer needs to be 200 words (1 Page). Once the answers are submitted, the tutor will check and assess the work.
