Dynamic Stress-Strain Measurements on Misers Bluff.

Abstract

MISERS BLUFF, Phase II, Test 2 was the near simultaneous explosion of six 120 ton ANFO charges on the corner of a hexagon 100 m on a side. Soil stress and strain measurements at several depths were made 6 m from the array center and between two charges. During the compressive loading by the air blast, dynamic stress-strain curves were plotted where data are available. Comparing the two locations shows different material behavior. Also, the near surface stress gages did not reproduce the air shock structure indicating a peculiarity of the material or material-gage interaction process. The material in the test bed exhibited a large strain energy absorption for propagating stress waves. (Author)
