title: Theoretical Elastic Deformations of a 4-m Diameter Optical Mirror Using Dynamic Relaxation.
abstract: This paper describes the results of an elastic analysis of a 4-m diam mirror. The mirror is solid quartz with a large central hole, flat back, and spherically dished front surface (f/2.75 system). We solved the three-dimensional elastic equations by a technique known as dynamic relaxation programmed for a digital computer. In this way, the resulting deformation of the optical surface is found for any proposed support system at any desired orientation of the mirror.
