摘要: Abstract This study examined the buckling of spherical caps fabricated under different conditions wall-thickness reduction. The were using photosensitive resin and had a base diameter 150 mm height 41.1 mm; they subjected to uniform external pressure. In total, 42 caps—6 with full thickness reduction 36 partial reduction—were through rapid prototyping; after their surface wall measured, all tested collapse experimentally numerically evaluate properties, namely pressures modes. Moreover, effects site, magnitude, range on properties evaluated. Herein, experimental numerical results are comparatively presented in tables figures.
