Statistically Based Material Properties. A Military Handbook-17 Perspective

Abstract

This report describes statistical procedures and their importance in obtaining composite material property values in designing structures for aircraft and military combat systems. The property value is such that the strength exceeds this value with a prescribed probability with 95% confidence in the assertion. The survival probabilities are the 99th percentile and 90th percentile for the A and B basis values, respectively. The basis values for strain-to-failure measurements are defined in a similar manner. The B value is the primary concern of this report. Keywords: Structural properties; Aircraft design; Statistics; Material properties; Reliability; Design allowables; Material strength; Tolerance limit; Composite materials; Structural design.
