STRESS WAVES DUE TO EXPLOSIVE AND MECHANICAL LOADING OF LOW MODULUS PHOTOELASTIC MATERIALS

Abstract

A two-dimensional photoelastic study was made of the stresses produced in a square plate of low modulus material resting on one edge and subjected to either explosive or mechanical loading at the center of the opposite edge. Using the method of oblique incidence, the principal stresses were separated at various points on the line of stress symmetry. Normal and oblique incidence stress patterns were photographed at exposures of 1.3 and at a rate of 7500 pictures per second, approximately. Results are given for the period of time that it takes the initial stress wave to traverse the plate and reflect from the supported edge. The influence of the type of loading is discussed. (Author)
