Abstract

Three fields of photomechanics are discussed to show the effort required to generate models for scientific exploration of these fields. The approaches center about the fundamental principle that the proper design of an experiment requires scientific design of the model to be investigated. Examples are chosen from photothermoelasticity (which is a relatively new field now well established), photoviscoelasticity (which is essentially a brand new field requiring extensive research before it will be established), and strobelasticity (which is a new form of an old, stablished field). These three fields are applicable to investigations of structural, thermal and dynamic problems in rockets and re -entry vehicles. Therefore, in addition to examples of basic problems, demonstrations of practical interest are included. These depict thermal stresses in a box beam, stresses in a case bonded viscoelastic rocket grain, and the effect of impact on a re-entry vehicle.
