ABSTRACT
A preliminary variable space grid formulation is described for a thermally
loaded and deforming elastic body undergoing a change of phase. The model
is numerically simulated using finite difference techniques and some results
are compared with measured data.
INTRODUCTION
Electro-fusion welding (EFW) is a process for joining lengths of plastic pipe,
typically used for the transmission of gas or water. Essentially the procedure
involves first inserting two pipe ends to be joined into a electro-fusion fitting
containing an embedded heating coil. An interference fit between pipes
and fitting is not expected and so, at least initially, an air gap will be
present. A current is then passed through the coil, the temperature of which
increases due to Joule heating. The surrounding plastic material of the
pipes and fitting subseque
