On the load-bearing efficiency of open-cell foams: A comparison of two architectures related to two processes

Using a simple beam element, this study estimates the elastic stiffness of two isotropic open-cell foam architectures that approximate, respectively, the space between tightly packed fluid bubbles and that defined between densified solid particles, and fin ...

Variable stiffness material based on rigid low-melting-point-alloy-microstructures embedded in soft poly(dimethylsiloxane) (PDMS)

Dario Floreano, Bryan Edward Schubert

Materials with controllable stiffness are of great interest to many fields, including medicine and robotics. In this paper we develop a new type of variable stiffness material based on the combination of a rigid low-melting-point-alloy (LMPA) microstructur ...

Scaling of conductivity and Young’s modulus in replicated microcellular materials

Andreas Mortensen, Andreas Rossoll, Yves Conde

Scaling exponents for the conductivity and stiffness of replicated microcellular materials exceed commonly predicted values of 1 and 2. We show here that this is caused by the fact that, in replicated microcellular materials, the solid architecture varies ...

Shear mechanical characterization of balsa wood as core material of composite sandwich panels

Thomas Keller, Anastasios Vassilopoulos, Julia De Castro San Roman Fest, Michael Osei-Antwi

An experimental study was performed using Iosipescu specimens to evaluate the effects of parameters such as shear plane, density and adhesive joints on the shear stiffness and strength of balsa wood panels as well as the variation of ductility with respect ...

Influence of punching shear reinforcement on the flexural response of flat slabs

Aurelio Muttoni, Stefan Lips

Physical punching shear models such as the Critical Shear Crack Theory (CSCT), which is the basis of Model Code 2010 (MC 2010), describe generally the punching strength as a function of the slab deformation. Thus, the prediction of an accurate load-deforma ...

Cellular biocomposites from polylactide and microfibrillated cellulose

Pierre-Etienne Bourban, John Christopher Plummer, Razvan Cristian Neagu, Carole Boissard

This paper describes the production of "green" microfibrillated cellulose-reinforced polylactide cellular biocomposites using a wet mixing technique combined with super-critical carbon dioxide foaming. The effect of composition on the morphology, density a ...

Time-temperature dependence of thermomechanical recovery of cold-curing structural adhesives

Thomas Keller, Anastasios Vassilopoulos, Julia De Castro San Roman Fest, Omar Moussa

The thermomechanical recovery behavior of a commercial cold-curing structural epoxy adhesive was investigated. Exposing the adhesive to temperatures above the glass transition temperature T-g significantly increased the latter although the curing degree in ...

Plasticization of polylactide foams for tissue engineering

Pierre-Etienne Bourban, John Christopher Plummer, Matthieu Cuénoud

Supercritical CO2 foaming of amorphous and semicrystalline polylactides plasticized by blending with 20 wt% polyethylene glycol has been investigated as a means of producing low-stiffness bioresorbable scaffolds for tissue engineering. For a given set of f ...
