Large deflections of laminated beams with interlayer slips

Abstract

Abstract Purpose – This paper aims to discuss selected components of finite element (FE) implementation of the modelling approach proposed in Part 1 of this paper. To put forward a simple and efficient method of enhancing shear stress transverse distribution. To demonstrate model performance. Design/methodology/approach – Developed elements employ polynomial interpolation with hierarchic/bubble modes and use assumed strain method to suppress numerical locking. Findings – Using well‐established concepts of FE technology is shown to provide a simple and robust tool for geometric non‐linear analysis of laminated beams. Presented numerical results highlight the need of including shear deformations in geometric non‐linear analysis of laminated structures with large transverse anisotropy. Research limitations/implications – The proposed model is dedicated to geometric non‐linear FE analysis of laminated beams undergoing large planar displacements, subject to small strains and moderate interlayer slips. Originality/value – A versatile FE is provided for geometric nonlinear analysis of laminated structures with large transverse anisotropy.
