Abstract

Strengths of laminated composite pressure vessels are studied via both
analytical and mathematical approaches. An Axis-symmetric finite element
model of graphite/epoxy laminate pressure vessel is established by ANSYS
finite element software. Analytical techniques are presented to determine
the first-ply failure of laminated composite pressure vessels with different
lamination arrangements. A solution algorithm is proposed to investigate
the progressive damage and failure properties of composite Pressure vessel
with increasing internal pressure. The maximum Principal stress, are
validated with analytical and Mathematical for verification of algorithm.
The accuracy of the algorithm prediction of first-ply failure strength is
verified by the analytical data by ANSYS software.
