The evaluation of structural integrity involves the determination of a limit state. If there is plasticity, limit analysis theory takes place. The aim of this paper is to present a limit analysis formulation considering friction at the contact interf

Dynamic mechanical analysis (DMA) is one of the most common methods employed to study the materials’ composition and properties. However, the complex modulus estimates provided by DMA are well-known to show divergences between samples and loading c

The computational modeling of instrumented indentation tests used to characterize material properties is challenging. It is mainly due to the computational techniques demanded to couple the complex physical mechanisms involved, such as, for example,

One of the key-aspects to promote sustainability in the biofuels industry is concerned with the recycling processes of its residues. In this sense, a consolidated method of reusing such residues is given by their incorporation in polymeric and compos

This work explores the viscoelastic behavior of two types of polymeric foams: an open-cell melamine foam and a closed-cell polyurethane foam. Experimental measurements were carried out on a torsional rheometer to estimate the complex shear modulus as

The classical generalized formulations for nonlinear viscoelastic behaviour do not represent the state of the art of modelling elastomeric materials and significant effects observed on polyurethane elastomers are not accurately predicted such as the
