Mathematical modelling of orthotropic and isotropic ribbed shells deformation taking into account the creep of material When investigating the mode of deformation and stability of shells under the action of sustained load it is necessary to take into account that with time the creep property becomes apparent in the material. It leads to the decrease of real load carrying capacity discovered in the elastic behavior of material. 10.18720/MCE.9.9 mathematical modelling ribbed shells orthotropic ribbed shells isotropic ribbed shells creep of material https://engstroy.spbstu.ru/article/2009.9.9/ zhgoutov_modeli.pdf
