Dedicated UTM fixtures are available for composite laminate delamination and fracture toughness work, including setups intended for interlaminar fracture testing in Mode I (DCB-style) and mixed-mode I and II configurations.

Fixture selection typically depends on the fracture mode you need to measure, your laminate construction and specimen geometry, and how the specimen will be loaded and aligned (for example, loading blocks versus other attachment approaches). Matching the fixture to the method helps reduce bending, twisting, and grip-induced damage that can distort crack growth behavior.

For laminate and sandwich structures, labs often pair delamination and fracture fixtures with composite-appropriate tensile grips or related composite test fixtures when the program also includes shear, peel, or flexural checks as part of a broader damage tolerance workflow.
