This report presents the results of tests made to determine the effect of different types of configurations and notches on the tensile strength and fatigue strength of a typical epoxy laminate. Tension tests were first made of 13 groups of specimens having different forms. Based on the results of the...
This report presents the results of fatigue tests of an epoxide laminate subjected to axial loading. Direct stress tests were made at 0°, 15°, 30°, and 45° to the warp direction. Stress was applied at a frequency of 900 cycles per minute at zero mean stress on both unnotched and...
This report has been prepared as a supplement to Forest Products Laboratory Report No. 1823, "Fatigue Tests of Glass-Fabric-Base Laminates Subjected to Axial Loading." It presents a correlation of the fatigue data in the basic report with stress-rupture data on the same material reported in Forest Products Laboratory Report No....
