The calculation of net shapes is performed using the finite element method. A triangular element is developed for the modelling of the net. The main hypothesis is that the strain in each triangular element is constant, the net has only two directions of twine and the twines are elastic. The forces due to the tension in twines are described and calculated by a direct method. Results of the model based on such triangular elements are given. The comparison with a model where each twine is described as an elastic bar is quite good. Copyright © 1999 John Wiley & Sons, Ltd.
