Abstract

This study deals with experimental and numerical response of trapezoidal corrugated core sandwich panels made of ST37 subjected to oblique blast loading. Sandwich target plate is 270*270 mm that consist of front/ back plate with 1 mm and trapezoidal corrugated core with 0.7mm thickness. The experimental explosive was done at the end of four different blast tube with angle of 0°, 15°, 30° and 45°respect to sandwich target plate. The mass of explosive (C4) was 10g and the stand-off distance was constant at 300 mm. The results of numerical simulation, obtained using coupled Eulerian–Lagrangian (CEL) model at commercial ABAQUS/Explicit software. The results show good agreement between the numerical and the experimental values. The results show that with increasing angle of tilt from 0° up to 45°, the maximum displacement decreases. At the higher masses of explosive, this reduction in deformation will be greater than the lower masses of explosive. Also, due to directing a large part of the blast wave to out of the blast tube, the amount of plastic dissipation energy at the angle of 45 degrees is significantly reduced compared to other angles.

Highlights

  • With increasing the angle of the explosive charge deformation of the sandwich panel decreases.
  • Plastic energy of the plate for the mass of the charge with an angle of 45 degrees is significantly reduced compared to other angles.
