Finite element modelling of z-pinned composite T-joints

This paper presents a finite element model (FEM) to analyse the structural deformation, strength properties and delamination fracture behaviour of composite T-joints reinforced with z-pins. The FE modelling involves multi-level analysis of a pinned joint using unit cell and macro-scale structural models. Unit cell model is used to calculate the crack bridging traction loads generated by the elastic and interfacial friction (pull-out) stresses of...
