Abstract

This paper demonstrate the effectiveness of outer-cover of pressure vessel in order to prevent risk scinario in brittle fracture. Dimensions of a cover are determined by considering failure modes of plastic collapse and brittle fracture. Failure experiment with pre-cracked vessel can clearly show the effectiveness of the proposed vessel for fail-safe design.
