A survey was conducted to measure the total area of salt affected land in the Wongan-Ballidu Shire. Initially two survey methods were used: an intense on-farm survey and a broadscale road traverse survey. In the test area there was no net difference in areas of salt land detected by the two survey methods. and the remainder of the shire was surveyed by the road traverse method. Difficulties in objective delineation of areas of primary and secondary salinity precluded accurate determination of each, and only the total salt-affected area could be measured. The total area was 51,975 ha. representing 15.4% of the shire area. Detailed surveys of three 2080 ha sites in the shire showed that in the 18 years between 1958 and 1976 the area of salt land increased by up to 237% with the mean area within sites increasing from 206 ha in 1958 to 541 ha in 1976.

Contact Stress Distribution

In order to improve vehicle safety, the accurate determination of the tire's loading behaviour is necessary in the domain of vehicle dynamics. The interaction between the tire and the surface of the road must be understood thoroughly. A 3D finite element model of the tire-road has been built by using MARC software according to the actual construction of the 195/60R14 radial tire. The rebar model of the radial tire is employed to simulate the complex multilayer cord-rubber composites and directly define the cord directions varying with their positions. The geometric nonlinearity due to large deformation, material nonlinearity and the nonlinear boundary conditions from tire–rim contact and tire–road contact are also considered. The relationships between load and the tire deflection, the tire deformation, the contact stress distribution and the distribution of the contact friction force are discussed.
