We present a novel class of selective mass scaling (SMS) concepts in the context of explicit dynamic analyses of thin-walled structures using solid elements. The novel SMS schemes are based on the discrete strain gap (DSG) method [1], a method from the field of finite element technology (FET). Thus, they are denoted as DSGSMS schemes and they extend the initial work of [2] for shear deformable structural element formulations to the application in thin solid elements. We show that these novel DSGSMS concepts naturally preserve both translational and rotational inertia and possess high accuracy. Additionally, having non-linear problems including large rotations in mind, we show how efficient isotropic DSGSMS concepts can be developed such that the need for reassembly of scaled mass matrices is avoided.
