Failure criteria applied to ship structures subjected to explosive blast loadings
conference paper
Both the dedicated element methodology and the material model with damage have been implemented into the explicit code LSDYNA as separate user defined subroutines. The predicted failure of an bulkhead to deck weld using the dedicated element methodology is shown in Figure 5, only the innermost of the five elements (in a dedicated element group) is eroded from the calculation when failure occurs. In this case the β Ratio will vary along the length of the weld as the ratio of bending to membrane loading varies. © CIMNE.
