Probing Shells Against Buckling: A Nondestructive Technique for Laboratory Testing

摘要: This paper addresses testing of compressed structures, such as shells, that exhibit catastrophic buckling and notorious imperfection sensitivity. The central concept is the probing a loaded structural specimen by controlled lateral displacement to gain quantitative insight into its behavior measure energy barrier against buckling. can provide design information about structure’s stiffness robustness in terms force landscapes. Developments this area are relatively new but have proceeded rapidly with encouraging progress. Recent experimental tests on uniformly spherical axially cylinders, show excellent agreement theoretical solutions. technique could be valuable procedure for prototype before it used range potential problems must examined solved. response highly nonlinear variety complications occur. Here, ...
