| Abstract |
The finite element method has been used to analyse the deformation behaviour of shadow masks during uniaxial tension. Shadow masks are perforated with a uniform triangular pattern of round holes or slots. The size of hole in the shadow mask varies with depth. In the analysis, the average hole size was used. The average hole size was calculated by averaging the hole sizes changing along the depth. Measured flow curves and apparent lateral strain-longitudinal strain relation were in good agreement with the FEM results calculated based on the plane strain at a larger ratio of thickness to ligament length and on the plane stress at a smaller ratio. |
