Abstract
A large structural analysis problem, involving the solution of 11448 equations with an average front width of about 350, was solved on a minicomputer. This mathematical model resulted from the application of the finite element method, using flat shell elements, to determine the stress levels induced in the carriage of a stacker-reclaimer due to design loads. Computer programs were developed for analysis; the frontal solution procedure with a restart facility and other modifications were used for the solution of the finite element equations. A scheme was developed and employed to solve such large problems on a minicomputer in spite of the limited computing speed and disc storage space available. Seven loads cases were analyzed and areas of high tensile and compressive stress identified.
