Structural performance of complex core systems for FRP-balsa composite sandwich bridge decks

Based on current fiber-reinforced polymer (FRP) composite construction principles, FRP decks fall into two categories: pultruded decks and sandwich decks. Sandwich decks comprise face sheets and either honeycombs or foams reinforced with internal FRP webs ...

Low-frequency wave propagation in post-buckled structures

Alessandro Spadoni, Florian Paul Robert Maurin

Nonlinear wave propagation in solids and material structures provides a physical basis to derive nonlinear canonical equations which govern disparate phenomena such as vortex filaments, plasma waves, and traveling loops. Nonlinear waves in solids however r ...

Stress–strain analysis of a toric pipe for inner pressure loads

Anton Schleiss, David Ferràs Segura

This research aims to enhance the knowledge on stress–strain states of a coiled pipe used for Hydraulic transient experiments. The membrane theory of shells of revolution has been applied for the description of axial and circumferential strains while an in ...

Cold neutron diffraction contrast tomography of polycrystalline material

Steven Luc X Peetermans, Andrew King

Traditional neutron imaging is based on the attenuation of a neutron beam through scatteririg and absorption upon traversing a sample of interest. It offers insight into the sample's material distribution at high spatial resolution in a non-destructive way ...

Anisotropic mechanical behavior and formability criterion for zinc sheets

Roland Logé

The mechanical behavior of zinc has been studied and linked to the formability of sheets. An anisotropic elastic-viscoplastic behavior law has been developed to take into account the anisotropy of the material. Anisotropy is induced by crystallographic and ...

An analytical model for lateral contraction of composite laminates subjected to partially uniform tension

Thomas Keller, Anastasios Vassilopoulos, Julia De Castro San Roman Fest, Behzad Dehghan Manshadi

An analytical approach to determine the in-plane stress field and thereby the lateral contraction of composite rectangular plates subjected to partially uniform tension is presented. This approach is based on the Green function hypothesis and is able to ac ...

First-principles model for phase stability, radiation defects and elastic properties Of W–Ta and W–V alloys

Nadine Baluc

Tungsten alloys are candidate materials for DEMO divertor applications because of their high melting point and low sputtering yield. We explore, using ab initio methods, the phase stability trend of W-Ta and W-V alloys. The available experimental phase dia ...

Elastomeric substrates with embedded stiff platforms for stretchable electronics

Stéphanie Lacour, Alessia Romeo

Stretchable electronics typically integrate hard, functional materials on soft substrates. Here we report on engineered elastomeric substrates designed to host stretchable circuitry. Regions of a stiff material, patterned using photolithography, are embedd ...

Noncontacting benchtop measurements of the elastic properties of shales

Thomas Emmanuel Blum

We evaluated a laser-based noncontacting method to measure the elastic anisotropy of horizontal shale cores. Whereas conventional transducer data contained an ambiguity between phase and group velocity measurements, small laser source and receiver footprin ...
