dc.description.abstractThe constraint is accepted as a measure of the triaxiality level at the crack-tip. Specimens with different a/W ratios present variation on the stress field ahead of the crack-tip. A stress relaxation can occur depending on the a/W values which is known as loss of constraint and has strong influence on the structural steels fracture toughness. Different approaches have been proposed to quantify constraint and to describe the effects of constraint variations on engineering fracture toughness characterized by J-integral, or equivalently the crack-tip opening displacement, CTOD. This paper presents the results of a numerical investigation, in which single-edge cracked bars in three point bend SE(B) and compact tension C(T) specimens, with different relative crack lengths, were systematically studied via detailed three-dimensional finite element analyses. A new parameter is then proposed to quantify crack-tip constraint.
