Abstract: A coupling member head includes a holder configured to hold a coupling member at an end portion on a coupling target member side in an axial direction and configured to approach or separate from a coupling target member, a pair of electrodes, tips of the electrodes being positioned closer to the coupling target member side than a coupling member holding region of the holder, and a retraction mechanism configured to move the electrode to a radial outside of the holder when the holder approaches the coupling target member.

Abstract: A method for optimizing orientations of an anisotropic material in a component. For example, the method overcomes the non-uniqueness and gimbal locking problems associated with using Euler angles to define the orientation by instead parameterizing the orientation using an orientation tensor that is a self-dyadic product of a direction vector. To avoid non-linear constraints in the mathematical design variables used in the optimization, isoparametric shape functions map the mathematical design variables to physical design variables, and the mapping ensures that various constraints associated with tensor invariants of the orientation tensor are satisfied even though these constraints are not directly imposed on the mathematical design variables. The physical design variables are used to model the component, whereas optimization is performed using the mathematical design variables.
