Passive tracer slowly decorrelating random flow large mean
2015/7/14
We consider the movement of a particle advected by a random flow of the form v + δF(x), with v ∈ Rd a constant drift, F(x) – the fluctuation – given by a zero mean, stationary random field and δ 1 s...
Propagation of Localization Instability Under Active and Passive Loading
Constitutive models Finite element method Limit analysis Banding Plasticity Localization Strain distribution Retaining walls
2015/7/1
The mechanical response of a solid continuum changes drastically as the deformation evolves from a diffuse state to a highly localized state. For this reason the subject of strain localization has rec...
