AbstractA simple field test of snow-slope stability is proposed, which allows decisions about a number of factors recently described by Conway and Abrahamson (1984). These include spatial variation of snow strength along a slope, and progression of failure from a localized initial failure. Strength within the snow slab is considered as well as that at its base. A snow saw is required for the test and, because a number of tests can be made in a few minutes, much information on the state of the slope can be obtained in a practical time.

The mechanics behaviour of connecting frame in aircraft composite cabin under static load can be expatiated through its dangerous key components. Initial damage and ultimate strength of the key component are studied using progressive damage method. Based on the strength prediction technique, the effects of composites ply angle and the structural layout on structural initial damage and ultimate failure are discussed to exploit the potential composite structural load carry ability. The numerical results show the ply angle modification can provide 26.3% increase on initial failure stress and 14.1% on ultimate strength. Farther structural layout adjustment can significantly increase the ultimate strength whereas go against the initial failure strength. The design scheme with concave boxes to cope with assembly demands is verified to be practical in joint structures by comparing with a connecting frame without concave boxes.

Efficient and accurate finite element (FE) modelling of bolted joints is essential for increasing confidence in the investigation of structural vibrations. However, modelling of bolted joints for the investigation is often found to be very challenging. This paper proposes an appropriate FE representation of bolted joints for the prediction of the dynamic behaviour of a bolted joint structure. Two different FE models of the bolted joint structure with two different FE element connectors, which are CBEAM and CBUSH, representing the bolted joints are developed. Modal updating is used to correlate the two FE models with the experimental model. The dynamic behaviour of the two FE models is compared with experimental modal analysis to evaluate and determine the most appropriate FE model of the bolted joint structure. The comparison reveals that the CBUSH element connectors based FE model has a greater capability in representing the bolted joints with 86 percent accuracy and greater efficiency in updating the model parameters. The proposed modelling technique will be useful in the modelling of a complex structure with a large number of bolted joints.
