alloya: Metallic Alloy Fatigue Crack Growth Test

In Auburngrads/SMRD.data: Statistical Methods For Reliability Data - Datasets

Description

Twenty-one specimens of an unknown alloy were subjected to the same cyclic load profile. Prior to testing, an initial crack (length = 0.9 in) was cut into each specimen to serve as a crack nucleation site. After each increment of 10,000 fatigue cycles the length of the crack was recorded. A specimen was considered to have failed when the crack length exceeded 1.6 inches, otherwise the test concluded after 1.2 million cycles.

Format
