Dual-beam polariscope and framing camera for dynamic photoelasticity

A dual-beam polariscope for obtaining simultaneous normal and oblique-incidence views for separating principal stresses, and high-speed photographic equipment and techniques for recording dynamic photoelastic stress patterns at rates up to 106 frames/s are described

Dynamic photoelasticity is concerned generally with the determination of transient stresses and strains in machine parts or structures subjected to impact or shock loading. Progress in this field has paralleled the development and application of new advances in high-speed photography. This paper describes the equipment, techniques and methodology used to study dynamic stresses in two-dimensional problems.
