Blast and explosion mitigation has come a long way from thick concrete and metal housings. … The result was the discovery of a high tensile strength to weight ratio polymer given the name Energy/Explosion Resistant Coating or ERC.
A bolted joint is the joining of two pieces of material using a bolt (or other threaded fastener) and a nut or threaded/tapped hole. It is expected that the bolted joint will be able to withstand the maximum applied forces to the joint over its lifetime.
The Queensland University of Technology’s (QUT) Robotics and Autonomous Systems research group led by Professor Matthew Dunbabin and Dr. Feras Dayoub have developed a reef monitoring robotic system that they call the RangerBot Autonomous Underwater Vehicle (AUV).
Choosing the correct rivet length for structural and nonstructural purposes is important for making full use of the material properties of the chosen rivet. Rivets are permanent mechanical fasteners that plastically deform to maintain axial loading on a joint.
Nature’s ability to evolve through natural selection, genetic drift, and other mechanisms has become an inspiration to modern (and historic) design choices. This process of designing based on natures problem solving through evolution has been given the name – biomimicry.
