Abstract

A comprehensive stress model of the filament winding fabrication process, previously implemented in the finite element program, WACSAFE, was implemented using the ABAQUS finite element software package. This new implementation, referred to as the ABWACSAFE procedure, consists of the ABAQUS software and a pre/postprocessing routine that was developed to prepare necessary ABAQUS input files and process ABAQUS displacement results for stress and strain computation.

The ABWACSAFE procedure has a structure and general flow pattern similar to the WACSAFE program. ABAQUS now performs the fundamental finite element procedures needed in the fabrication stress model. The ABWACSAFE pre/postprocessing routine utilizes many subroutines from the WACSAFE program. Some subroutines are used in their original form while many were significantly modified. New subroutines have been written as well.
