Hydrogen embrittlement and cycling durability

What is it about?

First of all, when hydrogen contacts a metal element for a sufficient amount time it diffuses into it and causes decreasing of materials' strength qualities (hydrogen embrittlement). Different structure components can be loaded periodically, i.e. by alternate applying load and withdrawing it. There is a special set of mathematical models of how such processes are going. They can be used by engineers to create stable and reliable structures (primarily of metal) being able to predict such damages. This work decribes experience of using one of the said models for analysing certain effects that are important for the area.

Why is it important?

This work differs form most others in that cloud technologies (Microsoft Azure Batch) were used to perform the computations. Also our research was based on a special hydrogen embrittlement model. Results of various works conducted with it are published in multiple journals in Russia and Europe. This model is quite uniquely 90% analytical, which basically means that it is efficient and modest in computer requirements.
