回顾了以往试图从纤维性质的角度建立纸的弹性模量理论的尝试。有人建议，通过考虑单轴应力的情况，以前的作者已经尝试了一个问题，太复杂了，以目前的知识状态。结果表明，等双轴应变的情况在理论上比较简单，对这种理论的验证也比较可靠。双轴理论的发展和弹性模量是写在纤维的模量和板的粘合面积。对一种纸浆的三种纤维粘结区的双轴模量进行了测量，这些公认的稀疏数据与理论一致。
A review has been made of the previous attempts to formulate a theory for the elastic modulus of paper in terms of fibre properties. The suggestion is made that, by considering the case of uniaxial stress, previous authors have attempted a problem that is too complex for the present state of knowledge. It is suggested that the case of equal biaxial strain is theoretically simpler and that verification of such a theory can be made more reliably. The biaxial theory is developed and the elastic modulus is written in terms of the moduli of the fibres and the bonded area of the sheet. The biaxial modulus has been measured for three levels of fibre bonded area for one pulp and these admittedly sparse data are in agreement with the theory.
