RISLower and Upper Bound Shakedown Analysis of Structures With Temperature-Dependent Yield Stress
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based upon the kinematic theorem of Koiter (1960, “ General Theorems for Elastic Plastic Solids,” in Progress in Solid Mechanics 1, J. N. Sneddon and R. Hill, eds., North-Holland, Amsterdam, ...
Modeling of the Behavior of a Welded Joint Subjected to Reverse Bending Moment at High Temperature
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper is concerned with the modeling of the behaviour of welds when subjected to severe thermal and mechanical loads where the maximum temperature during dwell periods lies in the creep ...
A Direct Method on the Evaluation of Ratchet Limit
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes a new linear matching method (LMM) technique for the direct evaluation of the ratchet limit of a structure subjected to a general cyclic load condition, which can be ...
On Shakedown, Ratchet and Limit Analyses of Defective Pipeline
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, the limit load, shakedown, and ratchet limit of a defective pipeline subjected to constant internal pressure and a cyclic thermal gradient are analyzed. Ratchet limit and maximum ...
On the Ratchet Analysis of a Cracked Welded Pipe
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the ratchet limit analysis of a pipe with an axisymmetric circumferential crack in a mismatched weld by using the extended linear matching method (LMM). Two loading conditions ...
Shakedown Analysis of a Composite Cylinder With a Cross-Hole
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, both the lower and upper bound shakedown limits of a closed-end composite cylinder with or without a cross-hole subject to constant internal pressure and a cyclic thermal gradient ...
