Creep failure of hierarchical materials
Mahshid Pournajar, Paolo Moretti, Seyyed Ahmad Hosseini +1
Creep failure of hierarchical materials is investigated by simulation of beam network models. Such models are idealizations of hierarchical fibrous materials where bundles of load-…

Failure precursors and failure mechanisms in hierarchically patterned paper sheets in tensile and creep loading
Mahshid Pournajar, Tero Mäkinen, Seyyed Ahmad Hosseini +3
Quasi-brittle materials endowed with (statistically) self-similar hierarcical microstructures show distinct failure patterns that deviate from the standard scenario of damage accum…

Enhanced fault-tolerance in biomimetic hierarchical materials -- a simulation study
Seyyed Ahmad Hosseini, Paolo Moretti, Michael Zaiser
Hierarchical microstructures are often invoked to explain the high resilience and fracture toughness of biological materials such as bone and nacre. Biomimetic material models insp…
