The Virtual Crack Closure Technique (VCCT) is a fracture analysis method based on linear elastic fracture mechanics (LEFM). It’s best suited for modeling brittle crack growth along predefined paths. VCCT works by assuming that the energy needed to close a crack is equal to the energy released when it extends—making it ideal for simulating crack propagation.

You can use VCCT in static, quasi-static, or implicit dynamic analyses (like high-speed impacts). It’s supported in Abaqus/Standard for 2D and 3D solid or shell models. VCCT can be applied to parts with regular geometry, orphan meshes, or a mix of both. Cracks are defined in the Interaction module, where you set up bonded surfaces to track crack growth.

In this short tutorial (under 10 minutes), you’ll learn how to set up a simple VCCT model in Abaqus to study crack behavior. The method is fast and well-suited for large-scale simulations. The video is straightforward, focusing on practical use so you can easily follow along and apply it using the provided output and Abaqus CAE file.
