Numerical investigation of the response of sandwich-type panels using thin-walled tubes subject to blast loads

On the ballistic and blast load response of a 20ft ISO container protected with aluminium panels filled with a local mass — Phase II: Validation of protective system

“…Several studies have lately been published in the open literature where the aim has been to design or validate blast exposed structures using various FEM techniques [7][8][9][10][11][12][13][14]. This is both required and important, since it is difficult, expensive and sometimes impossible to carry out blast tests on full-scale structures.…”

Dynamic energy absorption and perforation of ductile structures

“…These simple methods are particularly useful in the preliminary design phase. If, for example, an efficient core is required for a sandwich structure of the type studied by Theobald and Nurick [53], then the energy-absorption effectiveness factor, which is introduced in Section 4, could aid in the selection of the final core design, after which, if necessary, it could be explored in greater detail using a numerical scheme.…”

Simulation of a shock absorber with vertical buckling tubes welded in the longitudinal direction

“…The proposed design of this shock absorber must prevent buckling of shock absorber and reduction of the inner diameter. The use of thin-walled tubular structures in protective cladding was investigated in papers [10,11]. The authors propose a solution to the problem of blast protection using a sacrificial layer.…”
