Abstract:
... These experiments sought to empirically determine how the initial tightening force influences the ratio of the axial bolt force to the tensile load (load factor) and the load required to separate the joint interface (interface separation load) in tensile bolted joints of glued laminated timber. Load factor decreases with increasing initial tightening force; however, this tendency is reduced the gr ...

However, insufficient experimental data are available for models of this phenomenon. In this paper, we proposed a two-step experiment on cross-ply laminates to quantitatively study the influence of in-plane strain on the interlaminar fracture toughness. First, we ...
