Surface textures suppress viscoelastic braking on soft substrates

John Martin Kolinski, Martin Louis Francis Coux

A gravity-driven droplet will rapidly flow down an inclined substrate, resisted only by stresses inside the liquid. If the substrate is compliant, with an elastic modulus G < 100 kPa, the droplet will markedly slow as a consequence of viscoelastic braking. ...

The ratio of shear to elastic modulus of in-plane loaded masonry

Katrin Beyer, Bastian Valentin Wilding, Michele Godio

When designing unreinforced masonry buildings, the wall stiffness and, consequently, the masonry elastic and shear modulus E and G are essential parameters. Current codes provide empirical estimates of the masonry elastic modulus and a ratio between the sh ...

Stress concentration in sparse lattice structures

This report presents numerical results obtained through MATLAB simulations aiming at characterising the singularity of the stresses at a crack tip in a sparse, regular, linear elastic structure. The simulation algorithm is explained and validated by the re ...

Microstructure-based modeling of snow using the material point method and finite strain elastoplasticity

Johan Alexandre Philippe Gaume, Henning Löwe, Lars Kristoffer Uhlen Blatny, Stephanie Wang

The mechanical response of snow depends on its microstructural geometry. Parameters such as porosity and orientation (degree of anisotropy) are examples of microstructural parameters that can affect snow mechanical properties. Numerical simulations of snow ...

Influence of low curing temperatures on the tensile response of low clinker Strain Hardening UHPFRC under full restraint

Emmanuel Denarié, Mohamed Abdul Hafiz

The tensile response of strain hardening UHPFRC under full restraint, subjected to curing temperatures of 20 °C, 10 °C, 5 °C, was investigated for two types of mixes with silica fume; Mix I with pure type I cement and Mix II with 50% replacement of cement ...

Petrophysical properties of heavy oil-bearing carbonate rocks and their implications on petroleum system evolution: Insights from the Majella Massif

Carolina Giorgetti

In this work, we investigate the role of hydrocarbons in changing the petrophysical properties of rocks by merging laboratory measurements, outcrops characterization, and subsurface data focusing on a carbonate-bearing reservoir (Bolognano Formation) of th ...

Active biomaterials for mechanobiology

Mahmut Selman Sakar, Berna Ayse Özkale Edelmann

Active biomaterials offer novel approaches to study mechanotransduction in mammalian cells. These material systems probe cellular responses by dynamically modulating their resistance to endogenous forces or applying exogenous forces on cells in a temporall ...

Mechanical properties and cytocompatibility of dense and porous Zn produced by laser powder bed fusion for biodegradable implant applications

Andreas Mortensen, Ludger Weber, Karel Lietaert

In this work, the macrotexture of dense Zn produced by laser powder bed fusion (LPBF) was studied and the mechanical properties for different tensile bar orientations were measured. The compressive strength of LPBF Zn scaffolds with five different unit cel ...

Tissue deformation algorithm to estimate breast tumor location from prone-to-supine position

Nearly 15-40% of patients who undergo Breast Conserving Surgery (BCS) require a repeat procedure to ensure complete removal of the tumor resulting in increased healthcare costs and possible negative psychological impact on the patient. To ensure complete t ...

Poly(lactide)/cellulose nanocrystal nanocomposites by high-shear mixing

Véronique Michaud, Nicolas Candau, Oguzhan Oguz, Adrien Julien Demongeot, Mehmet Kerem Citak, Fatma Nalan Cetin

There is currently considerable interest in developing stiff, strong, tough, and heat resistant poly(lactide) (PLA) based materials with improved melt elasticity in response to the increasing demand for sustainable plastics. However, simultaneous optimizat ...
