Summary
The work presented in references [1,2,3] have demonstrated excellent performance of the finite
volume method in computational structural mechanics, which is encouraging for
the further application of the method to other complex structural problems. This
paper applies a cell centred finite volume method for the analysis of shell
structures. In the formulation presented here the membrane behaviour is considered.
In this way, the mid-surface of a shell is discretised into a number of arbitrary flat
elements. In the cell centred finite volume method each element is considered as a
control volume or cell, which its centre is located at the element centre. One cell is
connected to the neighbouring cells by its boundary faces. The cells' centres are
considered as the computational points. In the formulation presented three degrees
of freedom are assigned to the each cell centre, i.e. displacements along the

The test case concerns a cantilever cylindrical shell subjected to internal pressure loading. The results obtained are compared with the available reference solutions. The comparison between the predicted results and the reference solutions reveals that the method is able to predict accurate displacement fields. Future research aims to include the bending effects in the formulation. References
