Numerical Analysis of Interlaminar Stress Distributions around Hole in Thermoplastic Laminate

Abstract:

This paper investigates the interlaminar stress distributions at hole edge of notched thermoplastic laminates. Two numerical models of AS4/PEEK laminates with configuration of [±25]_S4 and [0/±45/90]_2S were built and studied by finite element code ANSYS. The results show: (1) The angle-ply configuration ([±25]_S4) may cause more severe concentration of interlaminar shear stress at hole edge; (2) the quasi-isotropic configuration ([0/±45/90]_2S) can lessen the stress concentration at hole edge.
