The design of structures using advanced composite materials such as fiber metal laminate requires an in-depth understanding of their deformation behavior and response to the discontinuities in the structures. In the present study, a GLARE kind of fiber metal laminate in 2/1 configuration was fabricated in the form of conical frustum. Three cut-outs of two different shapes such as circular and square were intentionally made at the center of the frustum at an angular distance of 120 . The quasi-static compression test was conducted to determine the crashworthiness characteristics of laminate frustums with cut-out and the results were compared with perfect frustum. The study showed that the laminate with cut-out undergone for inward buckling near the discontinuities. Apart from that, the delamination and outward buckling were noted in the edges of the cut-outs. The energy absorption of laminate frustum with circular cut-outs was observed to be better than square cut-outs. The performance of laminate frustums with cut-outs was ranked using Technique for Order Preference by Similarity to an Ideal Solution technique. A finite element analysis was carried out to simulate the deformation behavior of laminate frustum with cut-outs and the numerical results of deformation mode closely represented the experimental results.

“…This hybrid tool pin accelerates shear deformation and enhances workpiece material mixing and flow in the downward direction. Abhijit et al (2020) determined the best pin profile for friction stir welding using an optimization method [18] . Tapered (T), taper threaded (TT), and cylindrical threaded (CT) tools were taken for the investigation, and concluded that taper threaded provides better welding characteristics.…”

Friction stir welding is a solid-state joining process used to weld various materials. Tool life is an important consideration when welding strong metals with the Friction stir welding technique (FSW). The current research aims to calculate tool life by mathematical derivation and simulation using ANSYS transient structural analysis. There are two tool materials and five-pin profiles to consider. The calculated tool life using mathematical formulation is within 15% of the simulation outcome. Further changes are made to the simulation to make the tool life estimate more realistic under FSW’s operation. PcBN tool has superior mechanical properties over the tungsten carbide tool, so the procedure started with the tungsten carbide tool. The conical pin profile is giving 31466 cycles of tool life, which is 70 min run time while working at 450 rpm rotational speed. As a result, for high-strength materials joining, the tool must be chosen based on tool life parameters. The addition of a 1.5 mm fillet at the pin-to-shoulder junction has improved the tool life by 1147 cycles. The PcBN tool is simulated with a conical tool with new pin profiles of conical with grooves and cylindrical fillet with grooves. The maximum tool life of 94018 cycles is obtained for the conical PcBN tool.
