A method of spreadsheet calculation of plane strain slip line field solutions by the matrix operator method is presented. Excel and its add-in software ‘solver′ are used for determining the values of variables satisfying the boundary value problems of slip line fields. Two examples of known slip line fields of smooth die compression and indentation problems are calculated to determine if the Excel calculation can give correct results, by comparing with the previous data obtained by Collins and Dewhurst. Our results are in agreement with Collins and Dewhurst's data, confirming that the Excel calculated values are correct. CAD software is used to draw slip line fields and hodographs on the basis of spreadsheet numerical data and found to be suitable for drawing slip line fields and hodographs easily and rapidly.
