摘要： <正>应用弹塑性断裂力学理论 ,结合纸张的结构特性 ,推导出纸张的断裂韧性、抗张强度、零距抗张强度、平均最大孔径、抗张能量吸收之间的函数关系 ,利用该函数关系可以很方便地计算出纸张的断裂韧性。初步探索了纸张断裂机理。

Abstract: The function equation about paper fracture toughness,te nsile strength,zero-span tensile strength, maximum pore size and tensile energy absorption was proposed according to the theory of elastic-plastic fracture me chanics.The mechanism of paper fracture was also discussed.
