Book Description
A critical evaluation of three analytical approaches is made to determine their applicability and/or potential for analytically assuring airframe durability during the design stage. A suitable analytical format for quantifying durability damage is developed based on U.S. Air Force durability design specifications and durability analysis needs. Air Force durability requirements are briefly reviewed and discussed. Three potential approaches for durability damage analysis are conceptually evaluated and discussed: (1) Conventional Fatigue Analysis (Palmgren-Miner Rule); (2) Deterministic Crack Growth Approach; and (3) Probabilistic Crack Growth Approach. The resulting evaluation provides the prerequisite work needed to develop a durability analysis methodology. The probabilistic crack growth approach is found to be the most promising for developing the durability analysis methodology under Phase I.

Book Description
Orthochloronitrobenzene (OCNB) is a trace contaminant in Otto Fuel II (OFII), a nitrated ester used as a torpedo propellant by the U.S. Navy. In a published study, OCNB has been reported to produce multiple life tumors in male and female rats. The quantification of OCNB in OFII was performed by high pressure liquid chromatography. The OFII was performed by high pressure liquid chromatography. The OFII was found to contain 0.00165% ONCB and a distillate of OFII was found to contain 0.0009% OCNB. It was estimated that over a 12 month inhalation exposure to 240 mg/cum of OFII an animal would receive a total dose of 0.05 mg OCNB kilogram of body weight. This is insignificant compared to the total dose required for the previously published results. OCNB is not considered to be a factor in the outcome of the current studies.
