Resumen:
In this work we develop a method of straight lines for a
one-dimensional Bingham problem. A Bingham fluid has viscosity
properties that produce a separation into two regions, a rigid zone and a
viscous zone. We propose a method of lines with the time as a
discrete variable. We prove that the method is well defined, a
monotone property, and a convergence theorem. Behavior of the
numerical solution and numerical experiments are presented at the end
of this work.
