Application of an iterative Golub-Kahan algorithm to structural mechanics problems with multi-point constraints

Abstract Kinematic relationships between degrees of freedom, also named multi-point constraints, are frequently used in structural mechanics. In this paper, the Craig variant of the Golub-Kahan bidiagonalization algorithm is used as an iterative method to solve the arising linear system with a saddl...
