“…Moreover, the die land was demonstrated to have a negligible effect on damage and mechanical properties such as stress and strain state. Tang et al (2011) used the GTN model for the numerical simulation of damage evolution in multi-pass drawing. An optimization procedure, based on least damage accumulation principle, was proposed to define an optimal area reduction in a single pass drawing, with a constant semiangle (˛ = 4 • ).…”

“…giving zero stiffness) is commonly known as the element failure technique (Hambli and BadieLevet 2000;Saanouni et al 2004;Ko and Kim 2000). A numerical algorithm based on Cockcroft-Latham criterion (Choi et al 2010) and Gurson-TvergaardNeedleman damage model (Tang et al 2011) was applied to study the damage evolution in the cold extrusion and the multi-pass wire drawing process respectively. The damage criteria are classified into coupled approaches which incorporate damage accumulation into the constitutive equations (Tvergaard 1990;La Rosa et al 2001;Benseddiq and Imad 2008;Xue et al 2010) and uncoupled categories which neglect the effects of damage on the yield surface of materials (Ayada et al 1984;Alberti et al 1993;Wierzbicki et al 2005).…”

The objective of the present work is to predict the formation of chevron crack in copper wire drawing process. The first part of this paper is to determine the chevron crack formation initiated by a central burst inside the wire material using experimental tests. These results are compared with results from a series of numerical simulations using the CockcroftLatham fracture criterion. The second part of this work concerns the determination of a curve that divides the chevron and safe zones for a better wire drawing process. The conditions of central burst defects formation along the wire axis depend on drawing parameters and friction coefficient between the die and the wire. The friction coefficient is defined as a linear function of temperature rise which is measured close to the wiredie interface. The obtained results show that the friction A.

Microcracks in concrete can coalesce into larger cracks that further propagate under repetitive load cycles. Complex process of crack formation and growth are essentially involved in the failure mechanism of concrete. Understanding the crack formation and propagation is one of the core issues in fatigue damage evaluation of concrete materials and components. In this regard, a numerical model was formulated to simulate the thorough failure process, ranging from microcracks growth, crack coalescence, macrocrack formation and propagation, to the final rupture. This model is applied to simulate the fatigue rupture of three-point bending concrete beams at different stress levels. Numerical results are qualitatively consistent with the experimental observations published in literature. Furthermore, in the framework of damage mechanics, one damage variable is defined to reflect stiffness reduction caused by fatigue loading. S-N curve is subsequently computed and the macroscopic damage evolution of concrete beams are achieved. By employing the combined approaches of fracture mechanics and damage mechanics, made possible is the damage evolution of concrete beam as well as the microscopic multiple fatigue crack simulation. The proposed approach has the potential to be applied to the fatigue life assessment of materials and components at various scales in engineering practice.
