Product: Abaqus/Explicit
Benefits: You can now request the percentage of failed layers as element field output for a better failure status evaluation of composites.
Description: The output variable SFAILRATIO can be used to request a new element field output failure measure for composite shells. This failure measure is defined as
is the number of failed layers (a shell layer is considered failed when all of the section points in the layer are failed) and 
is the total number of layers in the shell. Values for SFAILRATIO are between zero (none of the layers failed) and one (all of the layers failed). SFAILRATIO is available for all failure models available in Abaqus/Explicit.References:
