SYNERGETIC APPROACH TO ESTIMATION OF RESISTIBILITY OF MEMBERS OF WELDED CONSTRUCTIONS TO SLOWED-DOWN FAILURE

There the process of slowed-down failure of members of welded constructions under the hydrogen action has been studied. The purpose is to develop the scientifically-substantiated means to estimate the resistibility of members of welded constructions to the slowed-down failure under the hydrogen action. The mathematical simulator of slowed-down failure of members of welded constructions has been developed and has been realized numerically on the basis of cynergetic approach. Two-parametric criterion to estimate the local failure of members of welded constructions with regard to the damageability of material by hydrogen has been developed. The computer program to design the change of local characteristics of materials under the hydrogen action and under the internal load, the criterion to estimate the local failure with regard to the hydrogen damage have been introduced. The study results are recommended to use in the research institutes and in the design offices, which are concerned with the questions of durability and failure of materials under the hydrogen action, which are concerned with the problems of cold cracking of welded constructions, to use during the estimation of residual life of critical industrial installationsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
