A one-dimensional simulation of an electrofusion welding process

A one-dimensional simulation of an electrofusion welding process based on finite difference method using control volume discretization is presented. Usually simulations of this nature are implemented with finite elements using a package, such as ABAQUS, with time consuming iterative computer code. This simulation is able to predict temperature and stress histories as well as giving the gap closure time of the welding process. The results of this simple simulation compared favourably with both experimental and ABAQUS values.
