Piezoresistive AFM cantilevers surpassing standard optical beam deflection in low noise topography imaging

Georg Fantner, Jonathan David Adams, Maja Dukic Pjanic

Optical beam deflection (OBD) is the most prevalent method for measuring cantilever deflections in atomic force microscopy (AFM), mainly due to its excellent noise performance. In contrast, piezoresistive strain-sensing techniques provide benefits over OBD ...

Thermoelasticity of Fe2+-bearing bridgmanite

Matteo Cococcioni, Andrea Floris

We present local density approximation augmented by the Hubbard-type correction calculations of high-temperature elastic properties of bridgmanite with composition (Mg(1-x)Fex2+)SiO3 for 0

Influence of boundary conditions and size effect on the drift capacity of URM walls

Katrin Beyer, Sarah Petry

In codes the drift capacity of unreinforced masonry (URM) walls is often estimated as a function of the failure mode and the aspect ratio. The empirical relationships are based on results from quasi-static cyclic tests on single URM walls, which were teste ...

Polymeric variable optical attenuators based on magnetic sensitive stimuli materials

Jürgen Brugger, Victor Javier Cadarso Busto

Magnetically-actuable, polymer-based variable optical attenuators (VOA) are presented in this paper. The design comprises a cantilever which also plays the role of a waveguide and the input/output alignment elements for simple alignment, yet still renderin ...

Creep behaviour of sandwich panels with rigid polyurethane foam core and glass-fibre reinforced polymer faces: Experimental tests and analytical modelling

Thomas Keller, Mário Alexandre De Jesus Garrido

This paper presents experimental and analytical investigations about the creep behaviour of sandwich panels comprising glass-fibre reinforced polymer faces and rigid polyurethane foam core for civil engineering applications. A full-scale sandwich panel was ...

Cell force measurements in 3D microfabricated environments based on compliant cantilevers

Jürgen Brugger, Giovanni Boero, Mattia Marelli

We report the fabrication, functionalization and testing of microdevices for cell culture and cell traction force measurements in three-dimensions (3D). The devices are composed of bent cantilevers patterned with cell-adhesive spots not lying on the same p ...

High-frequency multimodal atomic force microscopy

Georg Fantner, Adrian Pascal Nievergelt, Jonathan David Adams, Pascal Damian Odermatt

Multifrequency atomic force microscopy imaging has been recently demonstrated as a powerful technique for quickly obtaining information about the mechanical properties of a sample. Combining this development with recent gains in imaging speed through small ...

Effect of Load Distribution and Variable Depth on Shear Resistance of Slender Beams without Stirrups

Aurelio Muttoni, Miguel Fernández Ruiz

The work and findings reported in the paper are interesting to the discussers and will advance the understanding of the shear-failure mechanism of reinforced concrete (RC) beams. Some details need further discussion and clarification. In many cases, shear ...

Rotation capacity and stress redistribution ability of R-UHPFRC-RC composite continuous beams: an experimental investigation

Talayeh Noshiravani

The results of tests on two continuous composite beams combining a reinforced concrete (RC) beam with a layer of reinforced ultra-high performance fiber reinforced concrete (R-UHPFRC) are presented. The R-UHPFRC element acts both as a tensile membrane and ...

Ratio of mirror zone depth to flaw depth after failure of glass beams

Pieter Christian Louter

A precise estimation of the edge strength becomes an important issue when designing structural glass beams or façade mullions. However, in literature, the glass edge strength is poorly documented compared to the surface strength. In particular, the experim ...
