Abstract
Simplified defining relationships are being developed that will make it easier to determine the mechanical characteristics of PCM. The creep strain of a PCM in a plane-stress state is considered. The constitutive relations for PCM are obtained using the asymptotic analysis method.For the case of a complex stress state, the defining relations contain a large number of arguments (SSS invariants) of a different order of smallness, then they will be simplified by asymptotic analysis methods. To determine the parameters included in the constructed relationships, new approaches (parametric identification methods) to solving inverse problems will be adapted or developed.
