Long-term strength of ceramics under interrupted bending loading conditions

Scientific and Technical Section


Mathematical modeling is used to study the effect of stress redistribution within the cross section of a bent rod and the relaxation of residual stresses on the nature of the long-term-strength curves for structural ceramics when the load operates with interruptions.
