Fragility fractures cost European health care systems 56 Jun 07, 2021 · Professor Cyrus Cooper, President of the IOF, welcomed the announcement of SCOPE 2021 and urged European health authorities to prioritize the prevention of osteoporosis and fractures. This important publication clearly shows that osteoporosis is Europes major medical burden and the national health care system is very expensive.

Following a brief historical introduction to brittle fracture prevention for pressure vessel applications in various countries, the derivation of the toughness requirements of the European pressure vessel code are described. The background to the specification with respect to yield strength range and the treatment of sub-size Charpy is presented.
