TI  - Effect of Indenter Nose Shape and Layer Configuration on the Quasi-Static 
      Perforation Behaviour of Metal-Plastic Laminates.

AB  - This study investigated the perforation resistance behaviour of metal-plastic 
      laminates (MPLs) when they are indented by different nose shapes. Aluminium (Al) 
      and HDPE (high-density polyethylene) layers were bonded with a suitable adhesive 
      in an alternative manner to prepare bilayer and trilayer MPL configurations. 
      Quasi-static perforation experiments were performed with hemispherical, conical 
      and blunt indenters. The effects of nose shape, layer configuration and adhesive 
      on the force-deformation profile, perforation resistance capacity and failure 
      mechanisms were evaluated. The results indicate that for a monolithic layer, the 
      blunt indenter showed the highest perforation energy capacity. The conical and 
      blunt indenters facing Al backed by HDPE gave higher perforation energy. The 
      hemispherical indenter facing HDPE backed by Al was found to be more effective in 
      perforation resistance. Trilayer Al-HDPE-Al showed higher perforation resistance 
      than HDPE-Al-HDPE. Circumferential cracking, radial symmetric cracking and shear 
      plugging were the main failure modes for Al under hemispherical, conical and 
      blunt indenters, respectively. The adhesive contributed to an increase in the 
      perforation energy and peak force to failure in laminates. The adhesive was shown 
      to detach from the Al surface after Al fracturing through crack propagation, and 
      this effect was more pronounced when the indenter faced HDPE at the front of the 
      laminate.
