Testing method to determine a material's ultimate and yield strength by measuring how a test rod deforms under gradually increased tensile force. Beskrivning The process A specially designed test piece [1] is clamped at their ends to a tensile testing machine. The specimen is then pulled slowly out with increasing tensile force along its axis. As the rod is extended slowly a neck is formed at its center, and finally leading to failure. The machine records the current strain and tension and creates a stress-strain curve. Specimens with predetermined standard measure is used. Tensile testing Process films Advantages and disadvantages In comparison with alternative methods Easy to use, easy to prepare materials
