A progressive damage analysis based characteristic length method for multi-bolt composite joints

A Damage Model Reflecting the Interaction between Delamination and Intralaminar Crack for Failure Analysis of FRP Laminates

“…Many researchers focus on the transverse failure in the 0 • layer and the longitudinal failure in the 90 • layer, but the general cases such as angled matrix failure are less studied by the anisotropic damage model. In actual engineering applications, matrix cracks are properly angled with the mid-plane under a complex loading state [51,52], but are almost parallel to the fiber in every layer, so the matrix cracks parallel to the fiber are only considered in this work. An anisotropic damage model that reflects various kinds of matrix cracks and their interaction is presented here.…”

Microstructural characterization and failure analysis of 2D C/SiC two-layer beam with pin-bonded hybrid joints

“…However, as the size of the debonding area is random the accurate stress concentration factor (SCF) is hard to be known. In addition, although the stress distribution considering the interface damages can be obtained by progressive failure analysis with the aid of FEM [17][18][19], it is still complicated for practical use. In this paper, an empirical criterion was proposed in which two modified stress concentration factors (MSCF) were introduced.…”

A prediction method of the failure load and failure mode for composite pre-tightened tooth connections based on the characteristic lengths

“…Therefore, the research on the composite joint can develop the application of composite in the long span and high bearing capacity structures. Recently, the research of the composite joint mainly focuses on the composite bolt joint and composite adhesive joint [8][9][10][11][12][13][14].…”
