Abstract

|
|
|
| The topic of structural intensity analysis has been mainly focused on assessing the energy taking place on plate-like structures. This work presents a method which allows the same assessment on shells with arbitrary shape. By invoking the Kirchhoff-Love postulates, the current method enables the assessment of power transfer taking place on the shell's mid-surface from data available at one of the sample's outer surface. The mentioned data are the displacement vector components represented by the standard unit vectors of the Euclidian space and the spatial coordinates describing the studied shell. By including the assumption that the sample can be represented as an assembly of plates, the experimental displacement data are projected on a mesh, whose shape resemble the original analyzed shell. With this approach, the displacement fields could be properly differentiated along a predefined local coordinate system, leading to the necessary inputs for the structural intensity assessment. |
