О дрейфе и эффекте памяти нелинейно-упругой деформации вследствие ползучести для микронеоднородных материалов в условиях одноосного напряженного состояния

摘要

The drift phenomenon of nonlinear elastic strain arising due to creep in conditions of linear stress on the basis of structural model of Maxvilles generalized two-tier model type is studied. On the basis of modeling material it is demonstrated that is the whole spectrum of diagrams of elastic strain is located between two stationary conditions: the diagram at t=0 and the diagram corresponding to the stage of established creep, thus instantly-elastic deformation shows simultaneously the properties of mechanical memory and viscoelasticity. The modeling calculations illustrating the effect investigated is executed.
