In this section, the Abaqus progressive damage model and Helius PFA are each used to simulate the failure response of the composite conic structure. Helius PFA can be used in conjunction with 2-D continuum elements, shell elements, and 3-D continuum elements.

In contrast, MCT predicts constituent failure using the full 3-D constituent average stress state. The Abaqus progressive damage model predicts damage initiation and damage evolution based solely on the in-plane stress and strain components, ignoring the contribution of the transverse stress and strain components.In contrast, the MCT criteria in Helius PFA uses the constituent average stress states to predict failure in each of the individual material constituents. In the Abaqus progressive damage model, damage initiation and damage evolution of the material constituents (fiber and matrix) are predicted based on the composite average states of stress and strain.However, Helius PFA is specifically developed to efficiently handle this type of behavior and exhibits very robust convergence behavior. This type of instantaneous, discrete stiffness reduction normally poses severe convergence difficulties for finite element codes.

In contrast, Helius PFA imposes an instantaneous stiffness reduction determined by the particular constituent that failed. In the Abaqus progressive damage model, the material stiffness is gradually reduced as deformation continues to accumulate after the initiation criterion is met.
