Problem 10E

In a small-disc test a small, disc-shaped portion of a component is loaded until failure. The article “Optimizing the Sensitivity of the Small-Disc Creep Test to Damage and Test Conditions” (M. Evans and D. Wang, J. Strain Analysis, 2007:389^113) presents the results of a factorial experiment to estimate the effects of properties of the disc on the time to failure (in ms). The data in the following table are presented as a 25 design. The factors are A: hole diameter. B: disc diameter, C: disc thickness, D: punch head radius, and E: friction coefficient. Two other factors discussed in. the article are not considered here.
