The Finite Element Method (FEM) is widely used in civil and mechanical engineering to simulate the behavior of complex structures and, more specifically, to predict stress and deformation fields of structural parts or mechanical bodies.
The conclusion in this paper may enlighten the understanding of the fracture behavior of a complex structure and provide a valuable reference for fatigue limit prediction in engineering application.
The underlying principle of stigmergy is that by modifying the local environment, an individual can indirectly influence the actions of another individual at a later time thereby leading to the emergence of apparently coordinated collective behavior, accounting for the formation of complex structures, even by relatively simple "agents" that lack self-awareness or planning ability.
It is shown that the proposed relationship has a considerable ability to predict the apparent fracture toughness behavior in the ductile to brittle region of complex structures without need of conducting additional experimental fracture toughness tests.
To this end we have invited contributions on topics ranging from the development of complex structures and functions in systems ranging from cellular automata, genetic codes, and neural connectivity to social behavior and evolution.
The learning of the shape and appearance behavior of complex anatomical structures is of growing importance in the successful use of medical imaging data.
This paper describes the design, execution, and results of several experiments performed in order to investigate the behavior of complex interconnected structures found in biological neural networks.
The effectiveness (in terms of computational cost and accuracy of results) of the suggested linear numerical methodology, in predicting the compressive behavior of complex composite structures with inter-laminar damages, has been confirmed by cross-comparisons with the standard non-linear VCCT technique.
A 3D finite element model is employed consisting of glass fabric and surrounding epoxy resin matrix in order to predict the mechanical behavior of such complex structures.
