Buckling of an elastic rod embedded on an elastomeric matrix: planar vs. non-planar configurations

Pedro Miguel Nunes Pereira de Almeida Reis, Jia Liu

We investigate the buckling of a slender rod embedded in a soft elastomeric matrix through a combination of experiments, numerics and theory. Depending on the control parameters, both planar wavy (2D) or non-planar coiled (3D) configurations are observed i ...

A Microstructure-Based Model to Characterize Micromechanical Parameters Controlling Compressive and Tensile Failure in Crystallized Rock

Jian Zhao, Tohid Kazerani

A discrete element model is proposed to examine rock strength and failure. The model is implemented by UDEC which is developed for this purpose. The material is represented as a collection of irregular-sized deformable particles interacting at their cohesi ...

Thin ply composites: Experimental characterization and modeling of size-effects

John Botsis, Robin Amacher, Joël Cugnoni, Larissa Sorensen

Thin-ply composites are rapidly gaining interest in the composite industry, not only because of the larger design possibilities that they offer, but also because of positive size effects that have been shown to improve performance in various loading condit ...

Design for punching of prestressed concrete slabs

Aurelio Muttoni, Miguel Fernández Ruiz, António Manuel Pinho Ramos, Thibault Clément

Prestressing in flat slabs helps in controlling deformations and cracking under service loads and allows reducing the required slab thickness, leading thus to more slender structures and being therefore an economic solution for long spans. However, as a co ...

Influence of the geometry of partially-spanning joints on mechanical properties of rock in uniaxial compression

Jian Zhao

As jointed rocks consist of joints embedded within intact rock blocks, their behavior depends on the behaviors of the joints and the intact rock blocks. In a jointed rock, there are two levels of heterogeneity within the jointed rocks due to the difference ...

Determination of mechanical properties and full-field strain measurements of rock material under dynamic loads

Jian Zhao, Qianbing Zhang

We present a detailed experimental procedure for the quantitative determination of mechanical properties and full-field strain measurement of rock material under dynamic loads. Three kinds of testing methods, i.e., notched semi-circular bending, Brazilian ...

Evaluation of the tensile strength of SFRC as derived from inverse analysis of notched bending tests

Aurelio Muttoni

For the design of SFRC members, the most fundamental material property is its post cracking residual tensile strength. When relying on physical models to describe structural behaviour under load, the material laws must first be accurately established. If t ...

Experimental Investigation on Reinforced Ultra-High-Performance Fiber-Reinforced Concrete Composite Beams Subjected to Combined Bending and Shear

Talayeh Noshiravani

An experimental study on a series of composite beams combining a 250 mm (9.84 in.) deep reinforced concrete (RC) element and a 50 mm (1.97 in.) thick reinforced ultra-high-performance fiber-reinforced concrete (R-UHPFRC) element is presented. The specimens ...

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 ...

Microfabrication and characterization of an array of dielectric elastomer actuators generating uniaxial strain to stretch individual cells

Herbert Shea, Samin Akbari

Cells regulate their behavior in response to mechanical strains. Cell cultures to study mechanotransuction are typically cm2 in area, far too large to monitor single cell response. We have developed an array of dielectric elastomer microactuators as a tool ...
