A nonlinear block-coupled Finite Volume methodology is developed for largedisplacement and large strain regime. The new methodology uses the same normaland tangential face derivative discretisations found in the original fullycoupled cell-centred Finite Volume solution methodology for linear elasticity,meaning that existing block-coupled implementations may easily be extended toinclude finite strains. Details are given of the novel approach, including useof the Newton-Raphson procedure on a residual functional defined using thelinear momentum equation. A number of 2-D benchmark cases have shown that,compared with a segregated procedure, the new approach exhibits errors withmany orders of magnitude smaller and a much higher convergence rate.
