Brittle Fracture Testing

The strength of brittle materials, such as silicon and glass, is highly dependent on the lack of presence of micro cracks and surface defects such as scratches and chips. In these materials, the high level of stress at the tip of a crack cannot be relieved by plastic flow and so even very small defects can lead to low failure loads.

The Nordson DAGE 4000Plus test system’s low force capabilities combined with our specialist tooling, permit micro bend measurements to assess the severity of these defects. Three and four point and spherical bending can be performed with sample sizes as small as a 1mm square.
