Abstract
An acoustic emission (AE) measurement system, including a logarithmic amplifier, was applied in both normal and zero-span tensile test modes. The mechanism of tensile deforming and fracturing of paper was investigated, relating to the fiber-fiber bond failure and fiber failure. During straining, fiber-fiber bonds with low bonding energy begin to fail at first. Subsequently, fiber-fiber bonds with high bonding energy and the fiber themselves start to fail. The fiber failure fairly occurs during fracturing of paper.
