Аннотация: Abstract - The problem of the steady-state creep of a long narrow rectangular membrane with a proportional dependence of the transverse pressure on time is investigated. This membrane is located inside a high long rigid matrix of rectangular cross-section, in which the ratio of the height to half the width is not less than 1. A power relationship between the stress intensities and the creep strain rates of the membrane is used. Two variants of the conditions of contact between the membrane and the matrix are considered – ideal sliding and adhesion. The analysis is carried out until the time of almost complete adherence of the membrane to the matrix. A comparison is made of these times during sliding and adhesion for different values of the exponent in the constitutive equation and the relative height of the matrix.Keywords: membrane, the steady-state creep, a high rigid matrix, variable transverse pressure, ideal slip, adhesion.
