A finite-element approach for the analysis of pin-bearing failure ofcomposite laminates
Journal Title: Frattura ed Integrità Strutturale - Year 2014, Vol 8, Issue 29
Abstract
In this paper, a numerical home-made finite element model for the failure analysis of bolted jointsbetween fiber-reinforced composite laminates is presented. The model is based on an incremental displacementbasedapproach, it is hinged on the laminate theory and on a progressive material degradation governed by thefailure of composite constituents. The model has been applied to a pin-plate system comprising a monodirectionalfiber-reinforced laminated plate, and numerical results in terms of the bearing failure load have beensuccessfully compared with available experimental data. Aim of this paper is to evaluate the effectiveness ofRotem’s and Huang’s failure criteria in predicting the pin-bearing failure of bolted joints. The selected criteriaact at different material scale: the former operating at the laminate level, while the latter at the constituent’sscale. Proposed results seems to suggest that failure criteria accounting for micro-structural stress-strainlocalization mechanisms (for instance, Huang’s criterion) give a more accurate estimate in terms of pin-bearingfailure load.
