Abstract [en]
We present a new concept for selective mass scaling (SMS) in the context of shear deformable structural element formulations. The novel SMS scheme is based on a method from the field of finite element technology (FET), in particular the discrete strain gap (DSG) method [1], and is inspired by the recently introduced concept of intrinsically selective mass scaling (ISMS) [2]. So far, theoretical connections of efficient methods from the fields of FET and SMS have not been systematically investigated in literature. But, in this contribution, we show that this particular theoretical connection leads to novel SMS schemes of high accuracy. Our theoretical hypothesis is tested via a numerical example, which underlines the high potential of the proposed concept.
