Many times in testing space hardware it is desirable to quantify residual von Mises stresses and deformation in a test article which will ultimately be placed in a micro-gravity environment. When testing in a 1-g environment the stresses and deformations include the contributions due to weight. This investigation demonstrates a hybrid method used to identify the residual von Mises and deformations that reflect a no weight condition. To this end, an example of a hard X-ray space mirror is presented to demonstrate this hybrid method which combines finite element analysis with experimental profile measurements, made under gravity loading, on a prototype formed by electroforming a thin shell on a cylindrical aluminum mandrel.
