ISO 25217:2009 specifies a method, based upon linear elastic fracture mechanics (LEFM), for the determination of the fracture resistance of structural adhesive joints under an applied mode I opening load, using double cantilever beam (DCB) and tapered double cantilever beam (TDCB) specimens.
Abstract
Overview
ISO 25217:2009 specifies a standardized test method, based on linear elastic fracture mechanics (LEFM), for determining the mode I adhesive fracture energy (GIC) of structural adhesive joints. The method uses double cantilever beam (DCB) and tapered double cantilever beam (TDCB) specimens to measure both crack initiation and stable crack propagation under an opening (mode I) load. Results include a critical strain energy release rate and an R‑curve (G vs crack length) describing fracture resistance.
Key topics and requirements
- Test principle: Determination of adhesive fracture energy (GIC) using DCB and TDCB specimens and LEFM analysis.
- Specimens: DCB and TDCB geometries with controlled adhesive layer thickness (specified
