A new technique for coupling one dimensional beam elements to three dimensional bodies is described. The essence of the problem is to ensure compatibility of the displacements at the interface. This is achieved by equating the work done at the dimensional interface by the 3D nodes with the work done at the 1D node. This is carried out in a manner similar to(More)
Many analysis models utilize finite elements of reduced dimension. However, to capture stress concentrations at local details, it would be desirable to combine the reduced dimensional element types with higher dimensional elements in a single finite element model. It is therefore important in such cases to integrate into the analyses some scheme for(More)
A technique of idealising frame models using substructures is outlined. All joints are modelled in 3D but, using substructures, each 3D joint is converted to an equivalent stiffness element. The slender regions between the joints are modelled using beam elements. Coupling between the substructures and beam elements is carried out in a manner that conforms(More)
