Weld Cracking in Mutipass Welded Corner Joint
Journal of the Japan Welding Society, 1981 Lamellar tearing of opening type and root cracking occasionally occur in multipass welded corner joints.In this paper, the influence of welding methods such as submerged arc welding (SAW) and covered arc welding (SMAW) is investigated on the occurrence of these weld cracks. The main results obtained in this study are as follows.(1) When SAW is applied,

Hierarchical Artificial Muscle with Nonlinear Elasticity for Antagonistic and Cyclic Robotics
Advanced Science, EarlyView.We construct hierarchical muscles by plying nylon fibers around a heating wire. The hierarchical muscle shows a J‐shaped passive curve, which shows benefit in antagonistic muscle pair and work accumulation mechanism. We also develop a computational, first‐principle model to understand the physics of both active actuation stroke and passive J‐curve ...
