Direct Fem Limit and Shakedown Analysis with Uncertain Data
The structural reliability with respect to plastic collapse or to inadaptation is formulated on the basis of the lower bound limit and shakedown theorems. A direct definition of the limit state function is achieved which permits the use of the highly effective first order reliability methods (FORM) is achieved. The theorems are implemented into a general purpose FEM program in a way capable of ...
متن کاملShakedown analysis of soil materials based on an incremental approach
In this paper, an incremental technique based on cyclic loading is developed to implement shakedown analysis for soils in the framework of elastic-plastic analysis without utilization of the classical shakedown theorems. A finite element model together with the use of ABAQUS is established for soil structures subjected to cyclic loads, where the Mohr-Coulomb yield criterion with associated plas...
متن کاملthe role of task-based techniques on the acquisition of english language structures by the intermediate efl students
this study examines the effetivenss of task-based activities in helping students learn english language structures for a better communication. initially, a michigan test was administered to the two groups of 52 students majoring in english at the allameh ghotb -e- ravandi university to ensure their homogeneity. the students scores on the grammar part of this test were also regarded as their pre...
15 صفحه اولShape Optimization of Elasto-plastic Structures with Shakedown Constraints
An integrated approach for all necessary variations within direct analysis, variational design sensitivity analysis and shakedown analysis based on Melan’s static shakedown theorem for linear unlimited kinematic hardening material behavior is formulated. Remarks on the computer implementation and numerical examples show the efficiency of the proposed formulation. Important effects of shakedown ...
