Abstract
Shape memory alloy (SMA) is a novel functional material, which has found increasing applications in different engineering aspects. This research presents a finite element analysis of the potential benefits of SMA dowel bars on the jointed concrete pavements (JCP). With a 3-dimonsional (3D) Finite element modelling (FEM) and application of the damaged plasticity model, the tensile damage around the three types of SMA dowels are calculated, and the results are compared to conventional steel dowel bars in the JCP. It was found that SMA dowels considerably reduce the damages around the dowels through the concrete slabs. The load transfer efficiency (LTE) of the pavement equipped with these smart dowels are also have been discussed. To gain further understanding of the pavement behavior, a dynamic load was repeated a thousand times on the model. The damage and the LTE under repetitive loads have been investigated, and it is concluded that SMA dowels can maintain their load efficiency even under highly repeated loads, while causing less tensile damages to the pavement.
