Expert Commentary
Governs the Fracture Energy of Adhesives using the Contoured Double Cantilever Beam (CDCB) or Flat DCB. This is a Mode I opening test. The engineering metric is G-Ic, the critical energy release rate. MTO’s software includes a specialized module for crack-tip tracking. By correlating the load-drop with the crack length (measured visually or via compliance), we calculate the toughness of the adhesive. This is essential for the automotive and aerospace sectors to ensure that structural bonds won’t undergo catastrophic unzipping under impact or fatigue.
