Prolonged holding and cyclic loading indentation of aluminophosphate glass: kinetics of deformation

Abstract

The time-dependent mechanical behavior of aluminophosphate glasses (APG) (Li2O–Al2O3–BaO–La2O3–P2O5–RE2O3, RE = Dy, Tb) subjected to dynamic indentation under prolonged holding and cyclic loading conditions in combination with different loading rates is presented in this work. Analysis of the load-displacement (P-h) and displacement-time (h-t) dependences was applied to investigate the deformation peculiarities and kinetics of deformation in these conditions.
