Summary In this paper, a kinematic approach and an iterative procedure, earlier proposed for limit analysis, are adopted for shakedown analysis under variable repeated loading. Reference is made to three-dimensional structures of engineering relevance, such as pressurized pipelines and vessels with fluctuating pressure and with slot damages due, e.g. to pitting corrosion. The numerical performance of the solution algorithm is investigated, and the cost-effectiveness of the proposed direct shakedown analysis method is assessed and compared to that of time-marching solutions by up-to-date codes.
