    Abstract

    In the present work classical analytical models are used to describe the static stress–strain curves, low-cycle fatigue properties and fatigue crack growth behaviour of high-strength materials for use in tools for metal-forming processes such as cold forging and extrusion. The paper describes the experimental work carried out in order to establish the models. The constitutive equations represent the materials properties mathematically and define the relationships between load, deformation, lifetime cycles, crack growth rates and stress intensities.
