Annular Sector Element for Applied Element Method

Annular Sector Element for Applied Element Method Applied element method (AEM) is a numerical procedure that allows simplified modelling of structures. In AEM, the structure is modelled using rigid elements and springs. Any shape can be modelled by properly placing the springs, without increasing the computational effort. So far, AEM has not been utilised for the analysis of curved structures such as arches and rings using curved element. For the broad use of AEM, curved element is required. Arches are widely used as structural member. The analysis of circular ring is of interest today, as they are used as frames and parts of machines. In this paper, a new element is developed for the linear elastic analysis of curved structures. For this, a generalised two-dimensional annular sector element with infinite number of springs is considered. The element is used for both static and modal analyses of arches and rings. The results are compared with available analytical results, and good agreement is observed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of The Institution of Engineers (India): Series A Springer Journals

Abstract

Applied element method (AEM) is a numerical procedure that allows simplified modelling of structures. In AEM, the structure is modelled using rigid elements and springs. Any shape can be modelled by properly placing the springs, without increasing the computational effort. So far, AEM has not been utilised for the analysis of curved structures such as arches and rings using curved element. For the broad use of AEM, curved element is required. Arches are widely used as structural member. The analysis of circular ring is of interest today, as they are used as frames and parts of machines. In this paper, a new element is developed for the linear elastic analysis of curved structures. For this, a generalised two-dimensional annular sector element with infinite number of springs is considered. The element is used for both static and modal analyses of arches and rings. The results are compared with available analytical results, and good agreement is observed.
