Delamination and failure analysis features

Helius PFA software replaces traditional, generalized analysis methods and efficiently delivers advanced technologies for structural analysis and composite materials simulation.

    Advanced composite analysis

  • 3D weld line strength prediction New

    By using 3D visualization in Helius PFA software, you can help predict the strength reduction of weld lines. Helius PFA also lets you 3D weld locations from Moldflow software to structural finite element analysis.

  • Compression material response New

    Unfilled and fiber-reinforced plastics have significantly different responses in compression when compared to tension. Capturing the compressive response of components interacting with one another results in simulations that are more true to real states.

    Helius PFA allows the inclusion and differentiation of compressive material states, so your structural simulations have greater fidelity.

  • Progressive failure analysis

    Simulate the distinctly nonlinear progression of failure events more accurately in composite structures. Work beyond the limitations of linear elastic and first-ply failure methods. Helius PFA can efficiently handle material nonlinearity both pre- and post-failure. A unique material degradation scheme enables consistent and reliable prediction of global structural failure. 

  • Composite delamination

    Simulate intraply (fiber and matrix) and interply (delamination) failure simultaneously. Composite-specific technologies extend to Abaqus, MSC Nastran 2013, and ANSYS 15 cohesive elements to enable out-of-plane damage simulation. Predict the onset of matrix cracking and the start and propagation of delamination.

  • Reduced mesh sensitivity

    Use energy-based damage evolution to control the rate of material degradation for your composite structure. The rate of stiffness degradation typically decreases as the size of the element decreases. Specify the finite energy dissipation from failure of the fiber and matrix constituents to reduce the mesh sensitivity.

  • Multiscale analysis

    Select the right advanced composite failure criteria to predict distinct failure of the fiber and matrix constituents. Accurately simulate complex failure modes of composites with popular constituent-based methods, including Hashin, Puck, Christensen, LaRC02, and Multicontinuum Theory (MCT).

  • Element deletion

    Helius PFA works with Abaqus Standard and Explicit to remove elements from a simulation due to various failure modes. You can improve convergence, efficiency, and accuracy by running these realistic simulations.
