A three step recipe for designing auxetic materials on demand
(Nature, 2022)
Auxetics are an unusual family of materials that, for instance, when stretched in a particular direction will exhibit an expansion of the dimensions that are perpendicular to the applied stress; however, despite many known ...
Reciprocal frame structures, a first academic approach to sustainable structures
(International Association for Shell and Spatial Structures, 2017)
Computational simulation of a non-destructive testing technique for steel bar sizing in concrete structures using eddy current testing and neural networks
(2010-01-01)
This paper proposes a new type of non-destructive testing (NDT) for reinforced concrete structures, in order to identify the components of their reinforcement. In the proposed methodology a time varying electromagnetic ...
Tailoring vibration mode shapes using topology optimization and functionally graded material concepts
(IOP PUBLISHING LTD, 2011)
Tailoring specified vibration modes is a requirement for designing piezoelectric devices aimed at dynamic-type applications. A technique for designing the shape of specified vibration modes is the topology optimization ...

The use of piezoelectric materials in various applications, including the development of bio-inspired structures, vibration control, energy harvesting, among others, has been investigated by several researchers over the ...
Non-linear boundary element analysis of floor slabs reinforced with rectangular beams
(Elsevier B.V., 2007-08-01)
In this work, a numerical model to perform non-linear analysis of building floor structures is proposed. The presented model is derived from the Kirchhoff-s plate bending formulation of the boundary element method (BENI) ...
Dielectric and non-ohmic properties of Ca2Cu2Ti4-xSnxO12 (0.0 ≤ x ≤4.0) multiphasic ceramic composites
(2018-02-25)
Multiphasic Sn4+ substituted Ca2Cu2Ti4-xSnxO12 (0.0 ≤ x ≤ 4.0) ceramic composites were prepared by solid-state reaction. Their crystalline structure, microstructure, dielectric and non-ohmic properties were investigated. ...
