A control variate method for threshold crossing probabilities of plastic deformation driven by transient coloured noise
Harry L. F. Ip, Charlie Mathey, Laurent Mertz +1
We propose a hybrid method combining partial differential equation (PDE) and Monte Carlo (MC) techniques to obtain efficient estimates of statistics for plastic deformation related…

Drawing of Weakly Viscoelastic Fluid Tubes
Diandian Gu, Jonathan J. Wylie, Dongdong He +1
We explore the drawing of an axisymmetric viscoelastic tube subject to inertial and surface tension effects. We adopt the Giesekus constitutive model and derive asymptotic long-wav…

Coupled heat and fluid transport in pulled extrusion of cylinders
Eunice B. Yuwono, Yvonne M. Stokes, Hayden Tronnolone +1
In the fabrication of optical fibres, the viscosity of the glass varies dramatically with temperature so that heat transfer plays an important role in the deformation of the fibre…
