Influences of Long-period Hydrogen Storage on Structural Performance of Steel Vessel

摘要：

　　Presently,there are a significant number of investigations that study the influences of the hydrogen embrittlement on pressure vessels for hydrogen storage.But few of them consider the effects of helium-3 decayed from hydrogen.This paper studies the effects of the high-pressure hydrogen on mechanical behavior of a kind of steel pressure vessel by elastic-plastic finite element simulations,based on the explosion tests data of 4-,6-,14-and 17-year hydrogen storage vessels and relating experimental data of materials properties.Then the mechanical responses of the 50-year hydrogen storage pressure vessel are predicted.The results provide guidelines for design and evaluating hydrogen storage vessels.
