WebApr 14, 2024 · Damage indices can be classified based on different applications as: Local vs. Global: Local DI is an indicator of damage in an element, member, or limited part of the structure. The global DI on the other hand captures damage state in an entire structure. The global DI can be computed by weighted summation of the local DIs. WebFeb 15, 2024 · Kefal et al. [10] developed a four-node inverse quadrilateral shell (iQS4) element and adopted to demonstrate the iFEM formulation. Each node of the iQS4 element has six degrees-of-freedom (DOFs) in the local coordinates system (x, y, z) as shown in Fig. 1.Because of the inclusion of drilling rotations θ zi, the iQS4 element has less tendency …
