Shear lag analysis of strength of dual phase steels

Abstract

AbstractConsidering the similarities between structural distribution and deformation behaviour of martensite–ferrite dual phase steels with composite materials reinforced by short, discontinuous fibres, a new expression for the tensile strength of these steels was suggested using shear lag analysis, i.e. σ bDP = 1 K ( β 2 3 + 0 ⋅ 65 ) σ bM V M + σ bF
