Axisymmetric Elastoplasticity of a Temperature-Sensitive Functionally Graded Cylindrical Vessel
Based on Tresca’s yield criterion and small deformation theory, an axi-symmetric elasto-plastic thermal stress analysis for a cylindrical vessel made of functionally graded elastic perfectly plastic material is offered. ...
Influence of structural defects on the beneficial effect of autofrettage
, on the bene-
ficial effect of autofrettage loading. It is well known that autofrettage loading en-
hances the load carrying capacity of defect free pressure vessels. The results of this
study suggest that in presence of cracks...
Effect of stacking sequence on the temperature distribution in a composite multy-layered vessel
Effect of stacking sequence on the temperature distribution in a composite multy-layered vessel is studied.
Structural analysis for the autofrettage of FGM cylindrical vessels
Abstract— Recent technologies provide new opportunities for the construction of heterogeneous vessels with adaptable material compositions called Functionally Graded Materials (FGM). In order to benefit the damage tolerance ...
Influence of structural defects on the beneficiary effect of autofrettage
effect of autofrettage (AF) loading. It is well known that autofrettage loading enhances the load carrying capacity of defect free pressure vessels. The results of this study suggest that in presence of cracks, the localised near crack tip residual stress...
Interaction of Mechanical Loading with Residual Stresses in Pressure Vessel Structures
Assessment of the integrity of structures such as reactor pressure vessels is a critical issue
in relevant industries. In a full integrity assessment, the presence of initial residual stresses (RS)
needs to be taken into account...
Influence of initial stresses on cleavage fracture of pressure vessel containing a part circumferential surface crack
One critical issue in the integrity assessment of pressurised vessels to be addressed is characterising the influence of initial residual stresses (arising from fabrication processes especially around welds, where the ...
The effects of warm pre-stressing on cleavage fractur, Part I: Evaluation of Experiments
An experimental programme has been performed to characterise the mechanical parameters and the fracture response
of two steels, BS1501 and A533B. These are widely used in pressure vessel technology. The role of load history...
Elasto-Plastic Stress Analysis in Rotating Disks and Pressure Vessels Made of Functionally Graded Materials
A new elastio–plastic stress solution in axisymmetric problem (rotating disk, cylindrical and spherical vessel) is presented. The rotating disk (cylindrical and spherical vessel) was made of a ceramic/metal functionally ...
