Engineering and Technology Journal, 2016, Volume 34, Issue 11, Pages 2036-2046

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.

This paper presented an approach to design and implement a control scheme for hunting cages of predatory animals without hurting for scientific researchers or animals. In this paper, laser detection circuit is applied to detect target entering the cage and send signal to microcontroller to lock the two gates of the cage then send signal to alarm user. The bait is used to lure the target mounted on moving robot using ultrasonic sensor to determine the distance between the target and the bait and made it go in the cage.
