This ratio of dynamic to static flaw sizes existed at a temperature of 50 F below the DWTT 85 percent shear area transition temperature. When the material is at a temperature above its DWTT transition temperature, the critical flaw size for dynamic loading was greater than 95 percent of the critical flaw length for static conditions at the same pressure and temperature.\u003c\/p\u003e \n\n\u003cp\u003eSimilarly, it was shown that the failure pressure was reduced due to the dynamic initiation below the propagation transition temperature to between 81 to 86 percent of that for static failure. The reduction in failure pressure or change in critical flaw length is dependent on the pipe geometry, strength, stress level, and toughness.\u003c\/p\u003e","brand":"PRCI Store","offers":[{"title":"Default Title","offer_id":44367563194446,"sku":"220495","price":385.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/prci-store.myshopify.com\/products\/ng-18-10-r02-dynamic-initiation-of-a-flaw-in-pipes-1","provider":"PRCI Store","version":"1.0","type":"link"}
