A Method for Calculation of Face Gradients in Two-Dimensional, Cell Centred, Finite Volume Formulation for Stress Analysis in Solid Problems


Department of Civil Engineering,Guilan University


In this paper, a procedure is proposed for the evaluation of displacement gradients in a twodimensional,
cell centred, nite volume formulation for stress analysis in linear elastic solid
problems. Temporary elements with isoparametric formulations are used for calculation of the
gradients at the cell boundaries. In this way, stress continuity across the common face of the
two adjacent cells will be guaranteed. The formulation is veri ed by three test cases, in which
the proposed formulation shows good predictions.
