Abstract
Official abstract text for this publication.
A computer-implemented method of modelling a root-mean-square stress in a structure induced by a random load. The method comprises determining a modal correction factor based on data representing the eigensolution for the structure in free vibration. The modal correction factor characterizes the proportion of the random load, which is attributable to the root-mean-square response of the structure. Once the modal correction factor has been calculated, it is applied to data representing a stress in the structure due to a forced vibration to thereby determine the root-mean-square stress induced by the random load.
First claim
Opening claim text (preview).
The invention claimed is: 1. A computer-implemented method of modelling a root-mean-square stress in a structure induced by a random load applied to the structure, the method comprising: storing, in a non-transitory memory of an analysis engine, data representing an eigensolution of the structure in free vibration in a first mode of vibration; storing in the non-transitory memory, data representing a modal stress in the structure induced by the free vibration in the first mode o…
