TRAJKOVSKI, Jovan; KUNC, Robert; PERENDA, Jasenko  e  PREBIL, Ivan. Minimum mesh design criteria for blast wave development and structural response - MMALE method. Lat. Am. j. solids struct. [online]. 2014, vol.11, n.11, pp.1999-2017. ISSN 1679-7825.  http://dx.doi.org/10.1590/S1679-78252014001100006.

The Multi Material Arbitrary Lagrange Euler (MMALE) method is widely used method for numerical investigation of structural response under blast loading. However the method is very demanding for use at the other hand. In this paper are presented the results of the detailed numerical investigation in order to simplify some decisions contributing to the accuracy and efficiency of this model. The influence of mesh properties (particularly mesh size, its biasing and distance of the boundary (DoB) conditions from the deforming structure) on blast wave loading parameters and structural response is investigated in detail and based on the results minimum mesh design criteria is proposed. The results obtained are presented as a function of the scaled distance and additionally related to the radius of the charge. Validation studies were also done successfully.

Palavras-chave : Blast wave; blast response; blast loading; Fluid-Structure interaction.
