Failure Analysis of CPV with UMAT

Customer project carried out by CAE Assistant team

In  Failure Analysis of CPV with Semi-Geodesic winding with UMAT , the failure of Composite Pressure Vessel  wounded by Semi-geodetic method is investigated. In this analysis, Puck failure criterion as  the best criterion to indicate damage initiation is used in fiber and matrix separately. In this analysis, UMAT subroutine has been written and verified with related articles.As a result, contours shows composite pressure vessel which modeled with PYTHON scripting whether could undergo the internal pressure or not.
