Limit analysis is utilized to obtain upper and lower bounds of the punch pressure during indentation of a square punch on a square block and a circular punch on a circular cylinder. Reasonably close upper and lower bounds for the average pressure over the square circular punches are obtained and expressed as functions of the ratio of block width to punch width.
