Fracture response of externally flawed aluminum cylindrical shells under internal gaseous detonation loading

Abstract. Experiments were performed to observe the fracture behavior of thinwall and initially-flawed aluminum tubes to internal gaseous detonation loading. The load can be characterized as a propagating pressure jump with speed of 2.4 km/s and magnitude ranging from 2 to 6 MPa, followed by an expansion wave. Flaws were machined as external axial surface notches. Cracks ran both in the upstrea...

Fracture Response of Externally Flawed Cylindrical Shells to Internal Gaseous Detonation Loading

Experiments were performed to observe the fracture behavior of thin-wall and initially-flawed aluminum tubes to internal gaseous detonation loading. The pressure load, with speeds exceeding 2 km/s, can be characterized as a pressure peak (ranging from 2 to 6 MPa in these experiments) followed by an expansion wave. Flaws were machined as external axial surface notches. Cracks ran both in the ups...

Comparison of Fracture Response Of Preflawed Tubes Under Internal Static and Detonation Loading

The role of loading rate and fluid properties in the fracture of piping under internal explosions is an important issue for designers and accident analysis. This was examined by fracture experiments on thin-walled and preflawed aluminum 6061-T6 tubes. The tubes were 1) statically loaded with oil, 2) statically loaded with nitrogen, and 3) dynamically loaded with gaseous detonations traveling at...

Study on buckling of steel cylindrical shells with an elliptical cutout under combined loading

In this paper, simulation and analysis of thin steel cylindrical shells with elliptical cutouts under oblique loading were studied using finite element method. First, the numerical results were validated by the results of experimental test performed by an INSTRON 8802 servo hydraulic machine. Also, the effect of cutout angle (θ), cutout size, cutout position (L0/L) and cutout aspect ratios (b/a...

Optimization of Cylindrical Shells Under Combined Loading Against Brittle Creep Rupture

Optimal structural design of cylindrical shells under overall bending, torsion, tension and internal pressure in creep conditions is considered. The material is assumed to be governed by the Norton-Odqvist nonlinear steady creep law. Minimal weight of the shell is the design objective, radius and wall thickness are design variables, and the constraint refers to brittle creep rupture as describe...
