Thermodynamical Framework for Ductile Damage and Plasticity
AIP Conference Proceedings, 2010Many models employed for the prediction of plastic deformation rely exclusively on elastoplastic theories, disregarding significant effects of internal degradation [1]. Constitutive models based on the Continuum Damage Mechanics theory provide more realistic predictions since damage is taken into account as an internal variable.

The effect of initial damage on the dynamic ductile damage and fragmentation
International Journal of Fracture, 1995The hollow spherical model for the growth of the voids proposed by Carroll and Holt and Johnson is used. The effect of initial damage on the dynamic ductile damage and local fragmentation are investigated from the numerical results of dynamic damage velocity and fragment size versus material porosity at different initial damage ...

Radiation Damage Evolution in Ductile Materials
2015The problem investigated in the present work concerns the physical processes involved in radiation damage and the way they affect the mechanical properties of ductile materials. Multiscale modeling of evolution of radiation induced micro-damage in ductile materials subjected to periodic stress states in the inelastic range is presented.

Identification and measurement of ductile damage parameters
The Journal of Strain Analysis for Engineering Design, 1999The possibility of extending fracture mechanics concepts and design criteria to ductile failure is an issue that has attracted the attention of many researchers. Many models that address this are available nowadays. For these, two kinds of approach are widely used: the porosity-based model proposed by Gurson and the continuum damage mechanics (CDM ...

Micromechanical Characterization of Ductile Damage in DP Steel
Weight minimization triggered the automotive industry to introduce new advanced high strength steels that show ductile fracture by microvoid evolution under deformation, resulting in unexpected failure without significant necking. Therefore, an extensive study was initiated to gain insight on the formation and development of microstructural damage in ...Hoefnagels, J. +3 more

Fatigue Damaging Micromechanisms in Ductile Cast Irons
2006Ductile iron discovery in 1948 gave a new lease on life to the cast iron family. In fact these cast irons are characterised both by a high castability and by high toughness values, combining cast irons and steel good properties. Ductile cast irons are also characterised by high fatigue crack propagation resistance, although this property is still not ...
