Description: This case study shows how to choose materials to make spherical pressure vessels such that they yield before fracture or leak before fracture. The common requirement in engineering is that a design, if it should fail, should fail safely. Failure by fracture is not safe for pressure vessels.
Keywords: yield before break • yield before leak • fracture toughness • failure stress • pressure • yiled strength • stress • crack size • steel • copper alloys • aluminium alloys • titanium alloys • stainless steel • low-carbon steel • polymers
