Experimental and numerical investigations on low-velocity impact response of high strength steel/composite hybrid plate

摘要: Abstract Low-velocity impact tests were carried out on steel/short glass-fiber reinforced thermoplastic hybrid plates fabricated by a direct injection molding process. The response such as absorbed energy, peak force, dent depth and damage area was studied. A finite element model based the data obtained from dynamic static of constituent materials has been proposed to predict failure behavior under low-velocity loading, which is validated comparing experimental results. Using model, process thin interface between steel composite analyzed conveniently cost-effectively. It found that plastic deformation steel, fracture delamination are three main modes. After minor materials, occurred propagated rapidly. In addition, developed successfully investigate effects velocity, incident angle well material thickness plates. results in this study can support design optimization load-bearing metal-polymer (MPH) structures.
