Errors are estimated at less than 1% overall, and less than 1/2% at short crack lengths.K for a multiply-cracked, partially autofrettaged, internally pressurized thick cylinder may be obtained by appropriate superposition of the solution for the pressurized, non-autofrettaged cylinder and the ...
Internally pressurized cylinder illustrates biaxial stress states where correct determination of max requires taking 3 into account. Note that (1) for an element on the inside, 3 is negative and numerically equal to the internal fluid pressure and (2) for thin-walled cylinders 2 1/2....
The purpose of this paper is to present stress-intensity factors for a wide range of semi-elliptical surface cracks on the inside of pressurized cylinders. The ratio of crack depth to crack length ranged from 0.2 to 1; the ratio of crack depth to wall thickness ranged from 0.2 to 0.8; an...
For pressurized containers it is shown that stress distributions depend on Poisson's ratio which should be taken into account in a stability analysis since these structures are mostly vulnerable to the local loss of geometric stability. Introduction Bolts, rivets and location pins are some of the ...
11.3a. The von Mises cylinder is suitable to represent materials which are pressure-inde-pendent, as e.g. structural steel. The circular deviatoric plane demonstrates a constant shear capacity. The Drucker–Prager cone mirrors a hydrostatic pressure-dependent material, such as concrete. However, ...
An exact elasto-plastic analytical solution for large-strained internal pressurized thick-walled spherical vessels made of elastic-linear and nonlinear hardening material is derived in this paper. This solution is based on the notion of finite strains, the deformation theory of Hencky and the yield ...

In the initial elastic state the maximum principal stress (σ1) in a pressurized cylinder, which is in the hoop direction, occurs at the inner surface with the stress decreasing through the wall. Conversely, the Von Mises octahedral shear stress (σvm), which is generally assumed to control ...
2.The device for the low stress triaxial test according to claim 1, wherein the sample is made from a sampling cylinder in a cylindrical shape, the sampling cylinder comprises an inner shell and an outer shell, a surface roughness of each of the inner shell and the outer shell is less ...
