Abstract:

The creep of polymer materials is studied predominantly under conditions of static uniaxial tension. Established at present is the existence of elastic, elasto-elastic nonstationary and viscous stationary components of total creep strain. The total strain at a constant tensile load and temperature and also the duration of the loading are connected with each other. Liquid media under these conditions do not change the shape of the creep curves. It was of interest to clarify the possibility of using a equation for describing the creep of structural thermosoftening plastics with other forms of the stressed state in air and in liquid media. We studied the creep of polymers under normal conditions in air and in the model medium - the physiological solution 0.9 solution of nacl in distilled water under static bending and compression.
