Prediction of the corrosion cracking of structures under the conditions of high-temperature creep

Autor: O. K. Morachkovskii, Yu. V. Romashov

On the basis of the continual model of corrosion crack growth proposed earlier and the well-known incremental-type creep theory, we make an attempt to predict the corrosion cracking of structures under the conditions of high-temperature creep. We pro
