|The paper summarized some experimental main results of dynamic buckling under increasing compression load. The buckling behavior of 304 stainless steel was investigated using Euler and Johnson formulas, which is the most commonly used in industrial applications. It has been verified that metallic materials can exhibit non-linear buckling behavior with mechanical properties dependency. This behavior yield a non-linear model which based on Hong’s model but using the mechanical properties with cycles to failure. It was observed that the proposed model gave safe predictions while the Hong’s model yields non satisfactory predictions of critical buckling loads and also design electrical LASER alarm system to avoid the failure occurs in the specimen when access to critical buckling load.
