Due to the complexity of composite material, numerical methods are generally utilized in
their analysis and design. Commercial finite element (FE) codes, such as ANSYS and
ABAQUS, allow the implementation of user subroutines in the program, which provides the
advantage of using high meshing and solving technologies besides the improvement of
materials and/or elements models. Nonlinearities arise for many engineering problems, for
example, the progressive damage of a composite element that contains sources of stress …
