Abstract: A relatively simple experimental procedure for establishing the anisotropic yield characteristics of commercially available drawn metal tubes is described. Hill’s [4] extension of the Von Mises ...

Abstract: The paper describes a series of full-scale collapse experiments using X-42 and X-65 grade steel tubes. The initial geometric imperfections of the tubes were measured using a specially designed ...

Abstract: The collapse of long thick-walled tubes under external pressure is studied both experimentally and analytically. A two-dimensional nonlinear formulation of the problem is presented. The formulation ...

Abstract: A propagating buckle can be initiated in tubes under external pressure from localized imperfections. Once initiated a buckle will propagate with the result of flattening the tube behind it. The ...
