Abstract：

In production, the rupture limit problem for thin plate bulging is particularly prominent. Formula and the finite element simulation technology were used to compare the minimum thickness calculated value with the simulated experimental results based on Swift diffuse instability theory and Hill concentrated instability theory. The analysis and calculated results show that Hill model can predict bulging cracking tendency of thin stainless steel material, which is the right model for predicting the bulging limit for thin stainless steel material.
