Popis: A determination of the calibration curves of high-pressure devices is presented on the basis of an approximate calculation of the stressed state of points in the median plane (with respect to height) of a thin layer of an ideal generalized plastic material, compressed between rigid profiled anvils. A specific relationship is derived for the angle between the greatest principal stress and the median plane as a function of height and it is assumed that slip, retardation, and stagnation zones occur in the contact region. Recommendations are made in order to determine the boundaries of the stagnation zone for the case of profiled anvils. The difference between the results of the calculation and experimental data is no greater than 8%.
