WebJun 3, 2024 · The most common method for plotting a stress and strain curve is to subject a rod of the test piece to a tensile test. This is done using a Universal Testing Machine. It has two claws that hold the two extremes of the rod and pull it at a uniform rate. The force applied and the strain produced is recorded until a fracture occurs. http://web.mit.edu/course/3/3.11/www/modules/ss.pdf
