5. Conclusion Compared to the built-in 2D model available in the ABAQUS material library, the 3D PDM model can more accurately predict crack propagation directions at ultimate failure in FRP tubes under torsional loading. For the 3D PDM model with only a single layer of elements, the simulated torsional stiffness is correct, but the ultimate strength is incorrect; at least two through-thickness layers of elements are required to ensure a correct ultimate strength. The proposed 3D progressive damage model (3D PDM) demonstrates superior capability in predicting fibre aligned crack propagation in FRP tubes under torsional loading compared to the 2D PDM form ABAQUS’s material library.
