"Fracture Critical" to be featured in the next ISP Newsletter (September 2015)
Fracture critical, if you're in the profession of metal preservation, is a concept you will encounter, especially in historic metal truss bridges. Community groups, historians, craftsmen, or the average layman wanting to save a local historic metal structure, are sometimes stunned into silence when confronted with these two words.  Fracture critical members (FCM) are of great concern for the engineering community, and several examples of structure failures with loss of life have motivated research and the development of sound engineering approaches in regards to FCM issues.
