An approach will be presented to use the explicit time integration (crash code) for quasistatic analyses. In order to verify this appraoch a seat belt anchorage analysis was performed. The stable time-increment for the explicit time integration procedure is proportional to the square root of the mass density. If the analysis can be handled quasistatically the mass density becomes a free parameter and can be increased to increase the stable integration time-increment reducing thereby calculation- and turnaround-time. Different time dependent loading characteristics have been analyzed and tested in order to minimize dynamic effects. The appropriate loading curve together with a mass density increase served to approach a quasistatic solution. In this investigation the mass density value was increased by factors of 10 and 100. Results were assessed and compared to results using the original (unchanged) mass density and also to test results.
