Elastic-plastic analysis of slender first wall structures

摘要: Several current fusion first wall designs consist of slender channels. This type structure may be analysed by describing the bending behavior using a thin member theory and solving relevant boundary value problem for axial stresses due to end conditions load variations. Analytical finite element models are presented here that can treat range shapes constraints, have been implemented on microcomputers, fast cost-effective tools preliminary design. Representative analyzed, illustrating complex important influence irradiation creep.
