... those thought to be problematic. SCC is a delayed failure process in which cracks initiate and propagate at a slow rate (i.e. 10 −6 m/s) 4 until the stresses in the remaining ligament of the material exceed the fracture strength. SCC is a large problem for many manufacturers because it results...
