Abstract
AbstractThe two‐point bend test has been used extensively for optical fiber strength and fatigue measurements. This paper extends the theory of 2‐point bending to thin glass substrates. The key advantages of the 2‐point bend test are 1) the simplicity of a test fixture and its operation, 2) the uniformity of a bend stress along the width of a substrate, 3) the inverse relationship between a bend stress and parallel plate spacing, and 4) the non‐contact bending.
