ABSTRACT
The sign convention used for the stress and strain calculation is as follows compressive stress applied to a plane is considered positive, thus, tensile stress is negative; the normal components of strain are assumed to be positive if the deformation shortens the length of a side — a convention consistent. The boundaries of the cells are determined by the number of subdivisions specified for the individual formations and by the chosen spacing of the grid lines, respectively. By following the deformation of cells in time, the deformation pattern can be deduced, and then by comparing the displacement of cells defined and bounded by the same bedding surfaces, the development of strain can be mapped. In order to evaluate the stress field on the sediments spatially and with time, a number of rock properties must be specified.
