This study explores the dynamical behaviour of electromechanical systems used as vibration absorber. A nonlinear system is considered, with the nonlinearity coming from Duffing-type stiffness. The mathematical modelling ...

Modelling a rock mass in an accurate and realistic way allows researchers to reduce the uncertainty associated with its characterisation and reproduce the intrinsic spatial variability and heterogeneities present in the ...

In this work, nanostructured composites of polyetherimide (PEI) with addition of functionalized multiwall carbon nanotube (MWCNT) were processed via solution mixing. After processing, these nanocomposites were evaluated ...

Because of their application that normally demands high mechanical strength combined with low weight, the fibre/matrix interface became an important parameter concerning structural life. The problem of moisture absorption ...

In this work, the influence of bovine serum albumin (BSA) and methylcellulose (MC) as processing additives on the mechanical behaviour of the mullite-based cellular green bodies determined by diametral compression was ...

Plastisols, which are a blend of poly(vinyl chloride) resin and a plasticizer (DEHP), were used as a toughening agent of a resol resin in order to improve the mechanical properties. It was not possible to formulate resol ...

In this work, the mechanical behaviour of a set of resin- and pitch-bonded MgO-C refractories containing metallic additives was evaluated in laboratory tests at high temperature in a non-oxidant atmosphere. Commercial ...
