On the adequacy of standardized lightning current waveform for composite structures for aircraft and wind turbine blades

Marcos Rubinstein, Anastasios Vassilopoulos, Farhad Rachidi-Haeri, Aleksandr Smorgonskii

The standard lightning waveforms used for the testing of aircraft are based on downward lightning. However, there is evidence suggesting that lightning to aircraft is different from negative downward lightning. Also, carbon fiber composite materials are be ...

Grain boundary complexion and transparent polycrystalline alumina from an atomistic simulation perspective

Paul Bowen, Abhishek Tewari

Transparent alumina is often processed with sintering additives such as, Y, La, and Mg, in order to limit its grain growth at high sintering temperatures. Usually, these additives segregate to the grain boundaries due to their larger cationic size than Al ...

Stress Analysis of Unbonded and Bonded Prestressed CFRP-strengthened Steel Plates

Alain Nussbaumer, Ardalan Hosseini, Masoud Motavalli, Elyas Ghafoori

Numerous research studies are available in the literature on strengthening of steel members using carbon fiber reinforced polymer (CFRP) composites. Although it is clear that strengthening using prestressed CFRP plates has several advantages over non-prest ...

Structural concept and design of a GFRP-polyurethane sandwich roof structure

Thomas Keller, Sonia Yanes Armas

This work presents the concept and structural design of a 1000-m2 glass fiber-reinforced polymer (GFRP) sandwich roof replacing a timber roof over an indoor swimming pool. The advantages offered by the lightweight, multifunctional GFRP-polyurethane (PUR) s ...

Experimental verification of the method for producing a three-dimensional cross-pairs metamaterial structure based on a dielectric AlN cube

Przemyslaw Andrzej Gorski

This paper presents a method of manufacturing 3D metamaterial structures using laser radiation. Our proposed material, aluminum nitride (AlN), by interaction of a high-energy laser beam undergoes a direct metallization process, a result of which a conducti ...

Energy dissipation during delamination in composite materials - An experimental assessment of the cohesive law and the stress-strain field ahead of a crack tip

Luis Pablo Canal Casado

This paper presents detailed experimental information on mode-II delamination development in fibre/epoxy composite materials and provides observations about the process zone in the vicinity of the crack tip. It is shown that the energy dissipated in delami ...

Comparative Results From a National Joint Registry Hip Data Set of a New Cross-Linked Annealed Polyethylene vs Both Conventional Polyethylene and Ceramic Bearings

Background: Major concerns in hip arthroplasty concern the fate of bearing surfaces. Highly cross-linked polyethylene materials (HXLPE) currently demonstrate successful in vitro results with new technical procedures of cross-linking the polyethylene materi ...

Composite model for predicting the punching resistance of R-UHPFRC-RC composite slabs

Eugen Brühwiler, Maléna Bastien Masse

Adding a thin layer of Ultra-High Performance Fiber Reinforced cement-based Composite (UHPFRC), with or without steel rebars, over a Reinforced Concrete (RC) slab is an efficient reinforcement method for existing structures. The thin layer of UHPFRC serves ...

Rational design of fiber-reinforced hybrid composites: A global load sharing analysis

William Curtin, Varun Parameswaran Rajan

An analytical model based on global load sharing (GLS) theory is developed to guide design of fiber-reinforced hybrid composites with superior mechanical properties to single-fiber-type composites. The hybrid is assumed to comprise two types of fibers-low- ...
