Finite Element Contributions To Glass Manufacturing Control And Optimisation. Part 1. Creep Forming Of Flat Volumes

Finite element models seem to be an efficient design aid and optimisation tool for the manufacturer of flat and hollow glass products. In Part 1 of this paper, numerical simulations are first used for the analysis of reference critical forming cases of flat glass products: for example, the solution is numerically found for the separation during creep forming of a reference rear screen by way of local temperature increasing and/or corner radius input. In addition, pertinent information on manufacturing limits is defined in terms of bending radii for typical glass products, in order to meet the authorised design limitations, with regard to current manufacture potential.
