TWO-DIMENSIONAL DYNAMIC STRESS ANALYSIS IN A NONELASTIC MATERIAL.
Abstract
This program is one of a series of related programs whose ultimate objective is to provide technical information for the design of underground structures capable of withstanding the extremely high pressures generated by nuclear explosions. One approach to this problem has been the experimental study of stresswave propagation and interaction with discontinuities in soil-simulating media. In the present program a viscoelastic medium has been selected to closer simulate soil characteristics. The specific objective of this program was to develop materials, methods, and techniques for two-dimensional experimental stress analysis in viscoelastic polymeric materials. A great number of polymeric photoviscoelastic materials were investigated and one was selected as suitable for the program. This was plasticized Polyvinyl Chloride, a low modulus, transparent and birefringent viscoelastic material. Mechanical and optical properties under creep and relaxation conditions were determined.
