Abstract
A method of determining the effects of stress on a non-linear orthotropic ssile structure. Measurements of non-linear orthotropic strain, due to step-wise increasing stress in one of three orthogonal directions, are made. Non-linear orthotropic strain terms of the missile structure, in each of three orthogonal directions, are determined from the measurements. A compliance matrix is formed by using the determined strain terms. This compliance matrix is used in an iterative fashion of step-wise increasing stress, to determine three dimensional strain of the missile structure.
