PROCEDURE PROLONGING SERVICE LIFE OF LOADED STRUCTURE

摘要

FIELD: diagnostics of loaded materials, determination of value of residual life of loaded structure. SUBSTANCE: according to procedure prolonging service life of loaded structure is loaded with test load and if it does not break down its service life is prolonged by specified time. In correspondence with procedure absolute temperature T_tl of test, duration δt of test, absolute operational temperature T and service period are determined. Test load P_tl is determined from relation where U_o is initial energy of activation of break-down; R is universal gas constant; τ_o s; τ^*= 1 s. EFFECT: raised accuracy of determination of test load for prolongation of service life of tested structures serving both under corrosion and without it.
