Experimental method to predict critical buckling pressure of thin wall vessel using acoustic actuation and sensing

This paper introduces a novel experimental method using vibrational techniques to predict the critical buckling load of thin-wall pressure vessels without causing damage. Traditional numerical simulations often fail due to sensitivity to imperfections and boundary conditions, while static experiments risk structural destruction. Our approach combines finite element simulations with real-time tracking of natural frequency changes under varying loads, employing modal filtering techniques for precise identification. The paper includes simulations, experimental details, results, and discussions, offering valuable insights into using vibrational techniques for assessing pressure vessel integrity.
