ComPoLyX simplifies and extends the fai lure and strength analysis of laminated structures. It relies on the s tandard f in i te e lement software tools in the simulation of the complete structure. ComPoLyX enables the user to c r e a t e a n d v i s u a l i z e combinations of multiple failure criteria through data r e d u c t i o n .

ComPoLyX evaluates Inverse Reserve Factors (IRFs) as a primary measure for every given failure criterion. ComPoLyX computes IRFs at all integration points for all layers and elements in FE model of the composite structure. The IRFs allow easy comparison and combination of various failure criteria. Currently the following, fully configurable failure criteria are available:
Maximum strainMaximum stressTsai-Wu (2D and 3D)Tsai-Hill (2D and 3D)Hashin (2D and 3D)Puck (simplified, 2D, 3D)Core shear (sandwich)Face sheet wrinkling (sandwich)
For a given list of element sets, plies or laminate zones, ComPoLyX computes the combination of all active failure criteria and visualizes them in a single contour plot:
The color of each element indicates the maximum IRF for all configured criteria and all layersElement annotations show the active failure mode and the index of the layer with the maximum IRF
ComPoLyX provides a unique method to evaluate the normal stresses in thickness direction for curved laminates. This method relies on standard linear and quadratic shell elements. Normal stress evaluation enables the user to analyze 3D failure modes with ComPoLyX is available for 32bit and 64bit Windows Hashin, Tsai-Wu, Tsai-Hill or Puck criteria. and Linux platforms
ComPoLyX failure analysis can be applied to linear and quadratic layered shell elements in arbitrary Finite Element models created with ABAQUS, ANSYS or NASTRANComPoLyX can be operated through a powerful graphical user interface with OpenGL visualization and model specification treeComPoLyX employs multiple processors if available

ComPoLyX supports exchange of material data with ESAComp. Closer integration of ComPoLyX and ESAComp is under way. The ESAComp database and material definition capabilities (Database Module) will be utilized in ComPoLyX for efficiency and ease of use. Further on, the composites failure analysis capabilities will be merged to guarantee consistency in the different phases of the design process. Already now the ComPoLyX failure analyses are compatible with ESAComp.
