We study size effects in the fracture strength of notched disordered samples using numerical simulations of lattice models for fracture. In particular, we consider the random fuse model, the random spring model and the random beam model, which all give similar results. These allow us to establish and understand the crossover between a regime controlled by disorder-induced statistical effects an...

evidence acquisition a search of pubmed for studies on proximal fifth metatarsal fracture and jones fracture focusing on the classification and management was performed. the reference list of the retrieved articles was searched for additional related studies. conclusions lawrence and botte’s classification of proximal fifth metatarsal fractures is recommended by experts, due to its implication ...

This paper centres around an interdisciplinary research on the Atlantis-2 undersea fibre optic cable, seeking to plot deep entanglements between internet’s material infrastructure, colonial history, and submarine ruins. Through connecting interpreting a set of historical, archival, narrative elements Atlantis-2, this speculates genealogies telecommunication cabl...

The use of computer-assisted procedures before or during surgery provides orthopaedic specialists additional information that help them to reduce surgery time and to improve the understanding of the fracture peculiarities. In this context, the calculation of the fracture area is one of the main tasks in order to better comprehend the fracture. This paper presents the initial results of a method...

Concrete is a so called quasibrittle material which, despite predominantly elastic material response, exhibits in tension loading a stable non-linear fracture response, when tested under displacement control. The reason for the non-linearity is the development of a fracture process zone, in front of the crack, due to micro-cracking and crack bridging. The effect of the fracture process zone is ...

Recently published data for fracture in human humeral cortical bone are analyzed using cohesive-zone models to deal with the nonlinear processes of material failure. Such models represent the nonlinear deformation processes involved in fracture by cohesive tractions exerted by the failing material along a fracture process zone, rather than attributing all damage to a process occurring at a sing...

Mollusk nacre is a prototypical biological inorganic-organic composite that combines high toughness, stiffness, and strength by its brick-and-mortar microstructure, which has inspired several synthetic mimics. Its remarkable fracture toughness relies on inelastic deformations at the process zone at the crack tip that dissolve stress concentrations and stop cracks. The micrometer-scale structure...
