Strength and toughness of network materials: damage accumulation and controlling structural parameters

1° Seminar:

Research and innovation on materials & mechanics for paper, paperboard and paper products:

a series of seminars from worldwide experts

 

Many materials have a network of fibers as their main structural constituent and are classified as 'network materials'. This talk focuses on the relation between structural parameters of the network, its architecture and its strength and toughness. Several other structure-material behavior relations will be also reviewed. We observe and characterize the intermittent dynamics of rupture in stochastic soft networks. The outcomes of the study are (i) structure-property relations pertaining to material rupture, and (ii) a physical picture of gradual material degradation before macroscopic fracture.
