✦ Synopsis

Passive, fully grouted rock bolts are widely used in rock engineering. Based on the observations of the laboratory test phenomena, a three-dimensional elasto-viscoplastic constitutive model which takes special attention to the bolt's behaviour at a joint has been proposed. The model is justified by the laboratory test and is applied to the structure design of the upper gate bay of the navigation lock in The Three Gorges Project.

In electromagnetic field analysis, a systematic method of construction is presented for higher-order vector elements without respect to order. From the Helmholtz theorem, the vector basis functions are chosen. From the similarity with the scalar elements, the shape functions are determined by assign
