Abstract [en]

Selective mass scaling in explicit finite element analyses is a method to increase the critical time step by modifying the mass matrix while at the same time leaving the rigid body translational behaviour unaffected. In an earlier work it has been suggested to calculate the global acceleration vector as a = M̄-1 f where M̄ is the selectively scaled global mass matrix and where f is the global node force vector. However, dealing with large models, the mass matrix inversion is computationally costly and the storage of M̄ -1 requires a considerable amount of memory space. In this context it is here shown that an iterative solution technique, where M̄a = f is solved every time step, can be an attractive alternative to inverting the mass matrix.
