A micro-mechanics based extension of the GTN continuum model accounting for random void distributions
I. Holte, K. L. Nielsen, E. Martínez-Pañeda +1
Randomness in the void distribution within a ductile metal complicates quantitative modeling of damage following the void growth to coalescence failure process. Though the sequence…

Interaction of void spacing and material size effect on inter-void flow localisation
I. Holte, A. Srivastava, E. Martínez-Pañeda +2
The ductile fracture process in porous metals due to growth and coalescence of micron scale voids is not only affected by the imposed stress state but also by the distribution of t…

Steady-state fracture toughness of elastic-plastic solids: Isotropic versus kinematic hardening
Kristian J. Juul, Emilio Martínez-Pañeda, Kim L. Nielsen +1
The fracture toughness for a mode I/II crack propagating in a ductile material has been subject to numerous investigations. However, the influence of the material hardening law has…
