Abstract
In the present study the accuracy of the explicit dynamic approach for analysis of structures under severe loading is evaluated. Accordingly, three concrete slabs with dimensions of 750×750×30, 1000×1000×40, and 1250×1250×50 cubic millimeters are modeled in ANSYS LS-DYNA under two different explosion loading at two scaled distances of 0.518 and 0.591 m/kg1/3 and the accuracy of the results are compared with full scale tests both qualitatively and quantitatively. Amongst influencing parameters, the element size was considered and the function of analysis error was restored in terms of scaled distance and slab size. The results show that the maximum deformation, wreck radius and volume are larger for larger slabs at equal scaled distance.Furthermore, the numerical results are slightly larger than full scale tests for maximum deformation and wreck radius for all slabs and numerical results of uncoupled dynamic analysis are more accurate at larger scaled distances in equal explosion load.
