TENSION-TENSION FATIGUE LIFE DISTRIBUTION OF UNIDIRECTIONAL GRAPHITE/EPOXY COMPOSITE
-
Abstract
In older to study the fatigue life distribution of unidirectional graphite/epoxy composite,50 specimeus were tested at same stress level.(αmax=48 kgf/mm2).X2 test and check with the graph on the normal probability paper are used.If the logarithmic fatigue life of htese 50 specimens as a sample is taken from same population of Gaussian distribution.
