Numerical solutions of strain localization with nonlocal softening plasticity (2009, unknown): “Ill-posed problems can be regularized using various strategies, including visco-plasticity [1,3], Cosserat or micro-polar models [4– 6], higher-order gradient models [7,8] and integral type nonlocal models [9–14].”
Regularized formulation of the variational brittle fracture with unilateral contact: Numerical experiments (2009, methodology): “This point becomes even more hazy when considering the introduction of the unilateral contact constraint at the crack interfaces (see e.g. Ramtani et al., 1992; Comi, 2001).”
A damage model with evolving nonlocal interactions (2011, methodology): “A localisation analysis based on the propagation of acceleration waves (Pijaudier-Cabot and Benallal, 1993; Comi, 2001; Borino et al., 2003; Luzio and Bazant, 2005) is presented in this section.”
An extended FE strategy for transition from continuum damage to mode I cohesive crack propagation (2007, background): “Among several alternatives, the non-local continuum approach can effectively reproduce the damage process and its localization within a mesh-independent band [3], provided that the element size is small enough to resolve the band (at least three constant strain elements within the band).”
From the onset of damage to rupture: construction of responses with damage localization for a general class of gradient damage models (2013, background): “…(Pijaudier-Cabot and Bažant (1987); Bažant and Pijaudier-Cabot (1988); Pijaudier-Cabot and Benallal (1993)) and the gradient (Peerlings et al. (1996, 1998); Comi (2001); Comi and Perego (2001); Lorentz et al. (2011)) damage approaches, see also Lorentz and Andrieux (2003) for an overview.”
Recycled aggregate concrete (2017, unknown): “Therefore, fracture energy-based continuum approaches in the framework of the flow theory of plasticity, see a.o. Etse and Willam [9], Comi and Perego [10]; or of the continuum damage theory, see a.o. Bazant and Oh [11], Oliver [12], were recurrently considered in the literature to model brittle pos”
A new damage model based on non‐local displacements (2005, unknown): “[7] or non-local strain invariants [8].”
Computational applications of a coupled plasticity-damage constitutive model for simulating plain concrete fracture (2010, unknown): “[15,20]), and cohesive zone models (e.”
Phase field modelling of anisotropic crack propagation (2017, methodology): “This model has been proposed for the first time in the work of Ramtani et al. (1992), and applied to predict the behavior of rocks up to failure in the work of Comi (2001).”
The issues of the uniqueness and the stability of the homogeneous response in uniaxial tests with gradient damage models (2011, background): “The “classical” Kuhn-Tucker conditions, see for example (Comi, 2001; Geers et al., 2000; Lorentz and Andrieux, 1999; Lorentz and Benallal, 2005; Peerlings et al., 2001), are derived from the first order stability condition and the energy balance, while the main results of stability and bifurcation…”
