Computer simulation and FEM analysis of the stress-strain state thin plates thin-walled cylindrical shells, weakened by a circular hole in presence an annular inclusion functionally graded material (FGM) surrounding it, have been carried out. The influence dimensions FGM-inclusion law change its elastic modulus on concentration parameters shells vicinity is studied. distribution stress strain i...

This paper presents a comparison of numerical methods used to model large scale acoustic coupled fluidstructure interaction (FSI) problems for single and double-walled cylindrical shells. The finite element method (FEM) is used to model the structure while the fast multipole boundary element method (FMBEM) is used to model the fluid domain and both models are coupled on the shared boundary surf...

INTRODUCTION Composite materials are often used to reduce the weight of structures. In the automotive industry weight reduction is important because fuel consumption is directly related to vehicular weight. There is an increased concern for occupant safety during roadway accidents. Metals are currently used in car frames and integrated frame-body structures, and these and other metallic compone...
