The force-elongation diagram is essential for determining material ductility or brittleness. A long plastic deformation section after the yielding point indicates ductility, while a short linear section followed by a brief curve signifies brittleness. The identification of fracture mechanisms may not always align with the force-displacement curve due to the coexistence of different failure modes. Typical formulas related to stress-strain curves or fracture mechanics are used for analysis.
