DOI: 10.1016/j.cma.2021.114153
Abstract: Abstract Multi-rigid-body dynamic contact systems, in other words Non Smooth Contact Dynamics (NSCD) problems, generate some inherent difficulties to multivocal laws, which results in non-linearities and non-smoothness associated to frictional contact models. Recently, Primal–Dual Active… read more here.

DOI: 10.1016/j.compgeo.2019.103255
Abstract: Abstract Asphalt mixtures are complex multiphase materials showing a viscoelastic behavior. To assess the mechanical response of these materials, a typical practice is to perform a complex modulus test. An alternative to laboratory characterization is… read more here.
