    Notes: Abstract Interlaminar tensile shear tests are conducted to study the degradation mechanisms of electron irradiated glass or carbon cloth reinforced epoxy laminates. Interlaminar shear strength decreases significantly after the dose exceeds 3000 Mrad for glass/epoxy, but remains constant up to 12 000 Mrad for carbon/epoxy. SEM photos reveal that debonding of glass fibres and epoxy matrix (or degradation of silane coupling agents) plays an important role in the dose-dependent strength reduction of glass/epoxy laminates. The decrease in the interlaminar shear strength corresponds to that in the three-point bending strength. On the other hand, the SEM fracture appearance is almost dose-independent for carbon/epoxy laminates. In addition, some preliminary irradiation tests are conducted at −120° C to observe the effects of irradiation temperatures.

    Fatigue design of bolted joints taking into account reliability concepts (1987)
    Springer
    Experimental mechanics 27 (1987), S. 398-403

    Notes: Abstract A method is presented for fatigue design by comparing the load on the bolt in joints with the fatigue strength of the bolt-nut joints. Two types of bolted joints, cylindrical and T-flange joints, are treated as examples. Reliability concepts are introduced to the design. Fatigue tests of the above-mentioned bolted joints were also carried out to verify the applicability of the method. As a result, it appears that the fatigue behavior of threaded fasteners can be estimated to some extent by comparing the load on the bolt with the fatigue strength.
