A Novel Structural Health Monitoring Method for Full-Scale CFRP Structures

Polymer-based composite materials are used to manufacture ultra-light panels, massively introduced in the last decades in the aeronautical industry, as a potential solution to reduce the energy consumption and combustion emissions. Safety being the main co ...

An iterative analytical/experimental study of bridging in delamination of the double cantilever beam specimen

Anastasios Vassilopoulos, John Botsis, Behzad Dehghan Manshadi, Ebrahim Farmand Ashtiani

Large scale bridging in mode-I delamination of layered composites is an important toughening mechanism. While its extent depends on constituent materials, it is also influenced by specimen geometry. Here, an analytical approach is adopted to express the th ...

Testing strength and fracture toughness of hard second phases at micron scale

Andreas Mortensen, Marco Cantoni, Goran Zagar, Andreas Rossoll, Martin Guillermo Mueller, Václav Pejchal, Lionel Michelet

Local mechanical properties LMP 2015, November 12-14, 2014, Stará Lesná, Slovakia. Many alloys and composites combine a ductile matrix with discrete reinforcing phases, such as the ceramic fibers or particles that are used in metal matrix composites. It is ...

Non-convex optimization for robust multi-view imaging

Pierre Vandergheynst, Gilles Puy

We study the multi-view imaging problem where one has to reconstruct a set of l images, representing a single scene, from a few measurements made at different viewpoints. We first express the solution of the problem as the minimizer of a non-convex objecti ...

Multiresolution Information Mining for Pavement Crack Image Analysis

Rafael Eduardo Carrillo Rangel

Empirical mode decomposition (EMD) is a multiresolution data analysis method recently developed to cater to the inherent nonstationarity in real-world signals. A two-dimensional (2D) extension of EMD is used in this paper as a pavement distress image analy ...

Controllable coherent perfect absorption in a composite film

Olivier Martin, Shourya Dutta Gupta

We exploit the versatility provided by metal-dielectric composites to demonstrate controllable coherent perfect absorption (CPA) or anti-lasing in a slab of heterogeneous medium. The slab is illuminated by coherent light from both sides, at the same angle ...

Properties of nanocomposite film combining hard TiN matrix with embedded fullerene-like WS2 nanoclusters

Silviu Cosmin Sandu

We have developed hard self-lubricant coatings combining a hard matrix (TiN) and a self-lubricant phase in the form of inorganic-like WS2 fullerene. The nanoparticles were injected from the preparation chamber directly to the sample surface during reactive ...

Method and system for combining video sequences with spatio-temporal alignment

Martin Vetterli, Serge Ayer

Given two video sequences, a composite video sequence can be generated which includes visual elements from each of the given sequences, suitably synchronized and represented in a chosen focal plane. For example, given two video sequences with each showing ...
