Аннотация: Abstract - The problem of the steady-state creep of a long narrow rectangular membrane inside a rigid matrix with a proportional dependence of the transverse pressure on time is studied. It considers a long rigid matrix of rectangular section, in which the height is no more than half the width. Two variants of the conditions of contact between the membrane and the matrix are considered – ideal sliding and adhesion. In this paper, three stages of membrane creep are investigated. At the first stage, the membrane is deformed under the steady creep conditions up to the moment it touches the transverse wall of the matrix. The second stage ends when the membrane touches the longitudinal walls of the matrix. At the third stage, the membrane contacts the matrix along the transverse and longitudinal sides. The calculation is carried out until the time of almost complete adhesion of the membrane to the matrix. A comparison is made of these time values under different contact conditions and levels of proximity of the membrane to the matrix..Keywords: long narrow membrane, steady-state creep, low rigid matrix, transverse pressure, ideal sliding, adhesion.
