Patterns of load, elastic energy and damage in network models of architected composite materials
Christian Greff, Leon Pyka, Michael Zaiser +1
We investigate the role of architected thin films in the interfacial failure properties of bi-layer composites. Our results show that, while graded structures can be used to prescr…
Fiber bundle model of thermally activated creep failure
Stefan Hiemer, Paolo Moretti, Stefano Zapperi +1
An equal load sharing fiber bundle model for thermally activated breakdown is developed using transition state theory to describe the rate of elementary failures. The lifetime dist…
Tuning load redistribution and damage near heterogeneous interfaces
Christian Greff, Paolo Moretti, Michael Zaiser
We investigate interface failure of model materials representing architected thin films in contact with heterogeneous substrates. We find that, while systems with statistically iso…
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-…
Roughening and pinning of interface cracks in shear delamination of thin films
M. Zaiser, P. Moretti, A. Konstantinidis +1
We investigate the roughening of shear cracks running along the interface between a thin film and a rigid substrate. We demonstrate that short-range correlated fluctuations of the…
