Introduction
In the following paper for Explosives Engineering I discuss six of the basic,but very important,building blocks associated with the engineering of explosives.These properties include density,energy,pressure,temperature,gas product volume,and velocity of detonation.The aspects of these parameters that are reported on include their importance in the use and design of explosives,as well as their interlinking affect on each other.Also included in the paper are the descriptions and examples of theoretical calculations as well as the physical analysis of applicable property.All of this is important to know in order to efficiently utilize any explosive for the specific task given to an engineer.Through this composition of information it is my goal to broaden the understanding of these properties by my self as well as anyone else that might read the paper.Through this greater understanding of the backbone of explosives engineering,it will be easier to work with more complex topics,and with a greater comprehension of these topics.
This subject is especially important to me because of its application to future goals that I hold.While at school,my focus is to gain an understanding of the concepts surrounding explosives and energetic materials.Afterwards I want to be involved in the “invention”,synthesis,testing,and application of new energetic compounds.This class,and more specifically this paper,is the first big stride in my pursuit of a career in the field of energetic materials.
Density
Density (represented by ‘ρ’) is the mass of a compound per unit of volume,such as in g/cm3.The densities of each specific material vary greatly,but when used in explosives density can be changed in order to attain different magnitudes of thrust and brisance.For example,decreasing the density of an explosive will give a milder thrust effect and also decrease the velocity of detonation (VOD) [2].These effects are discussed more thoroughly in later sections.Some methods for altering the effective density of materials include pressing or casting,and mixing the explosive with a compound whose effect on the explosive reaction is either negligible or beneficial.Most densities used in calculations and reference tables are the Theoretical Maximum Density (TMD) of a compound.To find the TMD of a specific compound a simple linear relation can be used that will give you the answer with less than 2 - 3% error [3]:
ρ(TMD) = Ai – Ki(H)
Where H is the percent of hydrogen by weight,and Ai and Ki are constants that are dependent on the type of aliphatic compound being referenced.The groups and associated values for Ai and Ki are listed in Appendix 1.
