A model for 3D deformation and reconstruction of contractile microtissues

Mahmut Selman Sakar, Erik Mailand, Nikolaos Bouklas, Jaemin Kim

Tissue morphogenesis and regeneration are essentially mechanical processes that involve coordination of cellular forces, production and structural remodeling of extracellular matrix (ECM), and cell migration. Discovering the principles of cell–ECM interact ...

Colliders and conformal interfaces

Antonin Tancrède Amaury Rousset, João Miguel Augusto Penedones Fernandes, Marco Meineri

We set up a scattering experiment of matter against an impurity which separates two generic one-dimensional critical quantum systems. We compute the flux of reflected and transmitted energy, thus defining a precise measure of the transparency of the interf ...

Volume change characteristics of fine-grained soils due to sequential thermo-mechanical stresses

Alessio Ferrari, Rakshith Shetty

Know-how of volume change characteristics, VCC, of the fine-grained soils, exposed to thermal stresses, is essential for design of various thermo-active structures. These stresses are known to induce excess pore-water pressure, Δu θ , in the saturated stat ...

Following Microstructures during Deformation: In situ X-ray/Neutron Diffraction and HRDIC

Helena Van Swygenhoven, Efthymios Polatidis

The mechanical behavior of three engineering materials is studied employing in situ deformation methods. The study covers metastable austenitic steels with different stacking fault energies during multiaxial loading, a Ti-6Al-4V alloy processed by electron ...

In situ characterization of a high work hardening Ti-6Al-4V prepared by electron beam melting

Helena Van Swygenhoven, Karl Alan Sofinowski, Nicola Casati

A multi-phase Ti-6Al-4V prepared by electron beam melting and thermal post treatments has been shown to exhibit increased strength and ductility over standard wrought or hot isostatic pressed Ti-6-Al-4V. The mechanical improvements are due to a prolonged, ...

Load history effects in fibre-reinforced polymer composite materials

Abdolvahid Movahedirad

Today, it is widely accepted that fatigue is one of the most common failure mechanisms in structural components, and pure static failure is rarely observed. Engineering structures are subjected to complex mechanical fatigue loading histories, which cause d ...

Strain-induced network chains damage in carbon black filled EPDM

Nicolas Candau, Oguzhan Oguz

This paper presents an experimental method to follow in-situ the chains network alteration of filled vulcanized rubbers induced by deformation. Macroscopic damage is first investigated on a series of EPDM by quantifying void fraction via Digital Image Corr ...

Control of Hox transcription factor concentration and cell-to-cell variability by an auto-regulatory switch

The variability in transcription factor concentration among cells is an important developmental determinant, yet how variability is controlled remains poorly understood. Studies of variability have focused predominantly on monitoring mRNA production noise. ...

Cylindrical Dielectric Elastomer Actuator for Cardiac Assist Device

Jonathan André Jean-Marie Chavanne

This work has been triggered because of the need for a new way to relieve the heart. Current solutions are based on invasive systems. The main problem of such assistance is infectious risks. State of the art to define an alternative has allowed highlightin ...
