20.500.12556/RUL-186178 Napovedni model za analizo deformacij in strukturno optimizacijo pajkovih mrež A predictive model for the analysis of deformations and structural optimization of spider webs Izjemna zmogljivost pajkovih mrež izvira iz optimirane geometrijske zasnove mreže ter odličnih mehanskih lastnosti materiala pajkove svile. Razvit je bil napovedni model za analizo nateznih sil in strukturno optimizacijo mreže, ki temelji na analitičnih enačbah elastične verižnice; celoten problem pa je obravnavan numerično z Newton-Raphsonovo metodo. Postavljen je bil tudi eksperiment za analizo deformirane oblike obremenjenih mrež različnih geometrij. Ugotovljeno je bilo dobro ujemanje med numeričnimi in eksperimentalnimi rezultati, kar nakazuje na ustreznost napovednega modela za simuliranje obnašanja struktur pajkovih mrež ob predpostavkah, da niti prenašajo le osne natezne napetosti in da ni rotacije niti izven njihove lokalne ravnine pri obremenitvi. The exceptional performance of spider webs stems from their optimized geometric design and the excellent mechanical properties of spider silk. A predictive model was developed for analyzing tensile forces and structurally optimizing the web, based on the analytical equations of an elastic catenary; the entire problem is addressed numerically using the Newton-Raphson method. An experiment was also set up to analyze the deformed shape of loaded webs with various geometries. A good agreement was found between the numerical and experimental results, indicating the suitability of the predictive model for simulating the behavior of spider web structures under the assumptions that the threads carry only axial tensile stresses and that there is no rotation either within or outside their local plane under loading. pajkove mreže pajkova svila verižnica deformacija nelinearnost spider's webs spider's silk catenary deformation nonlinearity true false false [G.
