Mechanical Property Evaluation of Explosive Boards for High-Explosive Simulation Technique Applications.
Abstract
The high cost of the present method of explosive placement in HEST type tests led to the examination of explosive boards as a possible solution to this economic problem. The main objective was to find the maximum distances that these boards could span, supporting their own weight, and applying a safety factor of 2. These results were then applied to HEST cavity explosive spanning distances. Two types of explosive boards were available for testing--the Ensign-Bickford and the Thiokol boards. These boards were placed in a test frame and loaded to failure. The total load, distance spanned, and weight of board data determined the maximum spanning distances. The Ensign-Bickford board will span 8.17 ft in its weak direction (maximum span using a safety factor of 2); the spanning capability should be greater in the strong direction. The Thiokol board is isotropic and will span 14.23 ft with a safety factor of 2. Therefore, both boards will span the required HEST distances with the appropriate safety factor.
