The scordelis-lo roof
WebbTo illustrate the topology optimization of shell structures, the so-called Scordelis-Lo roof is then selected as an example problem. The analysis includes an assessment of the effect of eccentric stiffeners or ribs on optimum topology. … Webb6 maj 2024 · The formulation for the purely elastic case is verified using a spherical thin shell benchmark. Thereafter, the piezoelectric effect and vibration modes of a transverse isotropic curved plate are analysed and evaluated for the Scordelis-Lo roof problem.

The first six modes are depicted for the largest thickness to length ratio in Fig. 5 , it is observed that the modes vary between longitudinal bending and circumferential bending, and no membrane …
WebbCase 1 Scordelis-Lo roof problem. The Scordelis-Lo roof problem is shown in Figure 1. The cylindrical panel is loaded vertically with a uniform self-weight of g = 90. Both edges are fixed. Due to the symmetry, only one quarter of the panel is modeled. Three meshes are used in this analysis, as shown in Table 1. Webbelements. The subsequent Figure addresses the classical benchmark problem of the Scordelis-Lo roof under dead load. The corresponding problem description can be found in [1] or [4]. A standard Reissner-Mindlin formulation is compared to the hierarchic Reissner-Mindlin shell which is enhanced by a mixed approach for the membrane part.

Webb1 okt. 2005 · The Scordelis–Lo roof is subjected to gravity loading. The ends are supported by fixed diaphragms and the side edges are free (see Fig. 37). The vertical displacement of the midpoint of the side edge is the quantity used to assess convergence. These meshes have 2, 8, and 32 surface elements per side, respectively.
