Structural steels can be subjected to a range of stress and temperature conditions, and
accurate characterization of their limit states is a requirement for structural design. Yet data …

Fracture of steel at ambient temperature has been extensively studied. Such studies
developed efficient micromechanical fracture models, which can be used to predict the …

Thermomechanical processing of various rolling reductions was applied at intercritical
temperature of 790° C on a low alloy steel containing 0.09% C, followed by quenching in the …

Aeronautical structures such as landing gears, wheels or turbine shaft are designed to
withstand predefined loadings corresponding to critical scenarios. This work addresses the …

The effort of this study is to develop a simulation method to predict the effect of micro-
structural morphology in two-phase steel, Ferrite–Pearlite steel, on structural performance in …

It has been well known that ductile fracture of steels is accelerated by triaxial stresses. The
characteristics of ductile crack initiation in steels are evaluated quantitatively using a two …

A comprehensive combined hybrid numerical-experimental program is executed on three
advanced high strength steels (DP980, CP980 and CP1180) with the objective of validating …

This study presents the results of experimental investigation and models for ductile fracture
in the ASTM A992 structural steels subjected to high stress triaxiality. To this end, uniaxial …

For modern high strength steels, instead of metal instability, ductile damage triggered by the
formation of microvoids or microcracks resulting from the complex material microstructure …

The effect of triaxiality on the fracture toughness of a pressure vessel steel has been studied
over the brittle-ductile fracture mechanism transition. Specimens with a variety of widths …
