Estimation of Dynamic Stiffness Matrix of Welded or Glued Joints Using a Laboratory Fixture
SAE Technical Paper Series
Accurate quantification of welded or adhesive joints in automotive chassis structures is necessary before reliable models can be developed. Such joints undergo shear and rotational deformations, which must be characterized via diagonal stiffness elements and crossstiffness terms in order to describe static and dynamic problems. In this paper, a frequency domain decomposition technique is employed to extract static stiffness and viscous damping matrices of dimension 2 via analytical,doi:10.4271/2003-01-1710 fatcat:njqxzs4t6zek7dzp2ti2c4u2zy
