    Abstract : In developing trucks, cast components of low weight andhigh durability need to be developed and produced. Cast componentsrepresent an estimated 10-15 percent of the total weight of atruck. There is a strong coupling between the production processand the mechanical properties of a cast component such as it'sstrength. READ MORE

    Abstract : The efficiency of rail transport is attributed to low rolling resistance, which comes at the cost of high contact pressures between rail and wheel. Consequently, both the rail and wheel can be susceptible to fatigue crack initiation and propagation due to the resulting high stresses and large number of load cycles in service. READ MORE
