Cleavage fracture prediction in pressure vessel steels
Abstract
The fracture instability of the tempered ferrite-bainitic steels with precipitated carbide particles may be caused by two micromechanisms of cleavage failure (Strnadel et.al. 1986a,b).When the normal tensile stress σ(x) exceeds the microstructural cleavage strength σ fB the microcracks initiated in carbide particles start to extend into matrix ( Curry and Knott 1978 ): ( 1 ) https://www.w3.org/1998/Math/MathML" display="block"> σ f = π ⋅ E ⋅ γ eff B 2 1 - r 2 r 1 / 2
