...Hartwig Hübel The simplified theory of plastic zones (STPZ) was mainly developed to determine strain ranges and accumulated strains in the state of shakedown at cyclic loading between prescribed levels of loading. Kinematic hardening is an indispensable feature of the STPZ. The plastic limit load...

...Doo-Ho Cho; Young-Hwan Choi; Nam-Su Huh; Do-Jun Shim; Jae-Boong Choi In the present work, plastic limit load solutions are proposed for cylinders and plates with slanted TWC. Note that for cylinders, both slanted circumferential and axial TWCs are considered. These solutions are based on three...

... agreement. On the basis of the above results, a parametric analysis of the plastic limit moment for cylindrical vessels under in-plane moment on the nozzle was carried out, and an empirical formula is proposed. The results can serve as a supplement to the available data of plastic limit load for cylindrical...

...N. Li; Z. F. Sang; G. E. O. Widera The objective of this work is to study the plastic limit load of cylindrical vessels with different lateral angles θ under increasing internal loadings. Three full size test vessels with different structure dimensions were fabricated for testing. A three...
