The predictions of two numerical models of the deformation of fishing netting are compared. Analytical solutions are found to the differential equations that govern one of these models, and these solutions are used to evaluate the accuracy of both. There is very good agreement between the numerical solutions and the corresponding analytical values. The models are also applied to the deformation of networks where there is an in-plane shear resistance. Although there are no analytical solutions available, the similarity of the numerical solutions gives confidence in both methods.
