摘要： The invention discloses differing embodiments of finite element modeling methods utilizing mass distribution to model an object. In one embodiment, the finite element model of the object may be partitioned into sub-models. A determination may be made as to which elements in the finite element model are structural and as to which elements in the finite element model are non-structural. Mass properties for both the structural and non-structural elements in each sub-model may be determined. The significant non-structural masses within each sub-model may be selected and added to the finite element model. The remaining insignificant, non-structural masses may be incorporated onto the structural masses by scaling densities of the structural masses. The scaled structural masses may then be added to the finite element model. In other embodiments, objects are provided which were modeled utilizing finite element models under the invention.
