A dynamic polariscope for stress wave analysis.
Abstract
A polariscope for the study of the propagation of stress waves in birefringent sheets is described. Sensitive, fast-responding photomultiplier tubes, a laser light source, and a multiple channel oscilloscope were used for the simultaneous recording of the stress-optic data at several points of the target following impact. A method of separation of stresses and the computation of displacement, strain, and stress is given.
