Helius PFA supports multiple analysis conditions, including explicit and fatigue loading and supports multiple material types including chopped and continuous fibers, unidirectional lamina and various woven fabrics. A composite-specific material degradation method has been applied to handle the nonlinear, progressive failure of composites while improving solution convergence and simulation runtime. Multiple failure criteria are available to enable users to view damage effects at the fiber and matrix level and identify multiple modes of failure including delamination. Atits core, Helius PFA provides an efficient multiscale simulation that determines failure at the constituent level while also predicting structural,composite-level response. Helius PFA is anadd-on for commercial FEA programs that is designed to improve accuracy, efficiency and convergence in structural analysis of composite materials. The Utilities menu contains several additional tools such as calculators for determining fabric thickness, radius of curvature and spring back.
