The cohesive element approach to dynamic fragmentation: the question of energy convergence (2007, background): “Many examples of applications that utilize cohesive elements may be found in the literature [9–22].”
Cracking node method for dynamic fracture with finite elements (2009, unknown): “Overall, these methods show a significant degree of mesh sensitivity [12, 29], although Zavattieri and Espinosa [30] and Zhou and Molinari [31] have shown that introducing a degree of randomness in the cohesive strength ameliorates this problem.”
A micromechanical basis for partitioning the evolution of grain bridging in brittle materials (2007, unknown): “In a series of papers (Zavattieri and Espinosa, 2001; Zavattieri et al., 2001; Espinosa and Zavattieri, 2003a,b; Zavattieri and Espinosa, 2003) Zavattieri, Espinosa and coworkers examined the dynamic fragmentation of ceramic microstructures, with both digitized and synthesized microstructures being ”
A grain level model for the study of failure initiation and evolution in polycrystalline brittle materials. Part II: Numerical examples (2003, methodology): “Therefore, other microstructural features, such as nonuniform grain size and shape distributions, need to be included to capture the velocity histories and crack patterns observed in experiments (Zavattieri and Espinosa, 2001).”
Merger of structure and material in nacre and bone - Perspectives on de novo biomimetic materials (2009, background): “In order to model the interaction between the tablets, cohesive elements [66–69] were inserted on the tablet’s faces and sides.”

Cohesive zone modeling of dynamic failure in homogeneous and functionally graded materials (2005, methodology): “Various models have been proposed, their advantages, disadvantages and limitations being debated – see (Xu and Needleman, 1995, Geubelle and Baylor, 1998, Zavattieri and Espinosa, 2001; Pandolfi and Ortiz, 2002).”
