B. Debbaut et T. Marchal, 3-D TECHNOLOGY IN BLOW MOLDING - A NUMERICAL-SIMULATION, Journal of reinforced plastics and composites, 17(10), 1998, pp. 882-892
A numerical simulation is presented for the analysis of 3-D technology
in blow moulding process. The fluid parison is described by means of
a membrane element whilst a Lagrangian formulation is used for the gov
erning equations. The numerical algorithm is applied to the case of a
bent, three-dimensionally shaped tube. The contact between the guided
parison and moving mould parts is handled by a robust technique. Next
to the description of the parison motion, we concentrate on the predic
tion of wall thickness and extension components evaluated in both mach
ine- and cross-directions.
