Achieve more accurate non-linear simulation. Helius PFA maps manufacturing data from Moldflow injection molding software to structural FEA meshes for multiple parts in a structural assembly.
Multiple Modlflow studies can be leveraged to provide manufacturing data for large structural assemblies of plastic components. Helius PFA lets you:
Improve the simulation accuracy of injection molded parts by importing material data and fiber orientations through the Advanced Material Exchange. Transfer as-manufactured simulation data from Moldflow plastic injection molding simulation software to your structural model. Then, use this data to predict material nonlinearity due to plastic deformation and matrix cracking, and conduct a more accurate structural simulation early in the design cycle.
Use the Advanced Material Exchange to incorporate the effects of manufacturing into your structural simulation. Transfer residual strains from Autodesk Moldflow to include possible warpage from the injection molding process.
Use Advanced Material Exchange with multiple Moldflow materials, including fiber-filled plastics and non-filled plastics. Incorporate the material properties from the Moldflow database and the results of the manufacturing process into your structural simulation by transferring Moldflow results to your structural FEA code.
We designed Helius PFA for multiple material systems, each with its own failure modes accounted for in a progressive failure analysis. The software addresses unidirectional materials and a variety of woven materials, such as plain woven and 4-, 5-, and 8-harness satin weaves. It also includes a predefined set of both unidirectional and woven materials, with all data taken from published experiments.
Determine the life of your composite structure under fatigue loading with physics-based progressive fatigue life calculation tools.
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.
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.
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.
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.
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.
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).
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.
Gain the improved accuracy of a constituent-based composite failure method. Review an analysis of composite failure with the help of unique convergence technology specifically designed for composite materials.
Access a prepopulated material library, or enter your own material information. The material library comes with composite lamina material properties fully characterized for simulations. A Composite Material Manager tool provides a convenient interface for creating new material files. Use standard strength and stiffness properties to characterize your own unidirectional or woven lamina to use in composite simulations.
Add Helius PFA to your finite element analysis (FEA) platform for advanced composite materials analysis. With quick conversion of legacy models, you can easily begin to improve accuracy and efficiency in composite simulation and progressive failure analysis. Integrate the software using an intuitive user interface with a simple extension to your existing FEA investment, including Abaqus, ANSYS, and NASTRAN.
