Title of the Paper: Formulation of Elastodynamic Infinite Elements for Dynamic Soil-Structure Interaction

Number of paper pages: 10
Abstract: Abstract: - The paper is devoted to formulations of decay and mapped elastodynamic infinite elements, based on modified Bessel shape functions. These elements are for Soil-Structure Interaction problems, solved in time or frequency domain and can be treated as a new form of the recently proposed Elastodynamic Infinite Elements with United Shape Functions (EIEUSF) infinite elements. The formulation of 2D horizontal type infinite elements (HIE) is demonstrated here, but by similar techniques 2D vertical (VIE) and 2D corner (CIE) infinite elements can also be formulated. Using elastodynamic infinite elements is the easier and appropriate way to achieve an adequate simulation including basic aspects of Soil-Structure Interaction. Continuity along the artificial boundary (the line between finite and infinite elements) is discussed as well and the application of the proposed elastodynamical infinite elements in the Finite Element Method is explained in brief. Finally, a !
numerical example shows the computational efficiency of the proposed infinite elements.
