Abstract: Flat container is used to extrude large aluminum profiles.
Because of the inner-hole geometry of flat container is approximate to
ellipse, it is difficult to apply conventional conformal mapping method
of single-connect region to stress calculation. The stress calculation
formula and example of pressed flat container are given through complex
function of single-connect region and residue theory. By the comparison
with simulated result obtained by analysis, it shows that the theoretic
solution is in good accord with numerical solution and conformal mapping
method can be applied to practical stress calculation of flat container.
Furthermore, the method gives support to the design of flat container.
Key words: Conformal mapping Flat container Stress Theoretic solution
