20.500.12556/RUL-32210 Multilayered shell finite element with interlaminar continuous shear stresses a refinement of the Reissner-Mindlin formulation A finite element formulation for refined linear analysis of multilayered shell structures of moderate thickness is presented. An underlying shell model is a direct extension of the first-order shear-deformation theory of Reissner-Mindlin type. A refined theory with seven unknown kinematic fields is developed; (i) by introducing an assumption of a zig-zag (i..e. layer-wise linear) variation of displacement field through the thickness, and (ii) by assuming an independent transverse shear stress fields in each layer in the framework of Reissner's mixed varianational principle. The introduced transverse shear stress unknowns are eliminated on the cross-section level. At this process, the interlaminar equilibrium conditions (i.e. the interlaminar shear stress continuity continuity conditions) are imposed. As a result, the weak form of constitutive equations (the so-called weak form of Hooke's law) is obtained for the transverse strains-transverse stress resultants relation. A finite element approximation is based on the four-nodedisoparametric element. To eliminate the shear locking effect, the assumed strain variational concept is used. Performance of the derived finite element is illustrated with some numerical examples. The results are compared with the exact three-dimensional solutions, as well as with the analytical and numerical solutions obtained by the classical, the first-order and some representative refined models multilayered shells finite elements interlaminar equilibrium mixed methods večslojne lupine končni elementi ravnotežje med sloji mešane metode true false false Angleški jezik Angleški jezik Neznano 2015-07-10 10:13:09 2015-07-10 10:13:09 2022-11-21 15:53:16 0000-00-00 00:00:00 2000 0 0 Str. 843-874 N. 6 Vol. 48 2000 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 624.074.4:519.63 0029-5981 947041 6316039 Multilayered_IJNME_Brank_k.pdf Multilayered_IJNME_Brank_k.pdf 1 78910420C5F13E8D46A1B4869CB915FF 9230731a33a35c10db37af1816b36f6ca3f323bf8e9b0949fafb56ba7d2a743f 15cfd7fb-a1ae-11eb-a523-00155dcfd717 20.500.12556/rul/6af368de-a189-4b4c-8af2-855d618ec50b https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=85723 Fakulteta za gradbeništvo in geodezijo 0 0 0
