Experimental proof of the rheological model of viscoelastic softening medium with exponential creep kernel

S. V. Gorbunov

Samara State Technical University, Samara, Russia

Abstract: Behavior of densified laminated wood DSP-G is described by relations of rheological model of viscoelastic medium providing consideration of effects of material softening. Value of material's long–term strength limit corresponding to boundary between domains of stable (asymptotically limited creep) and unstable (development of tertiary creep) deformation is found. Comparison of calculated and experimental creep data and long–term strength limit data is executed. Correlation between calculated and experimental data is observed.

Keywords: viscoelastic material, exponential creep kernel, deformation stability, tertiary creep, densified laminated wood, experimental proof
