| Abstract: | Results on stress concentration in thin shells with curvilinear holes subject to plastic deformation and finite deflections
are reviewed. The holes (circular, elliptical) are reinforced with thin-walled elements (rings, rods) of different stiffness.
A numerical method of solving doubly nonlinear problems of statics for shells of complex geometry is outlined. The stress
distribution near curvilinear holes in spherical, cylindrical, and conical shells under statical loading is studied. The numerical
results are analyzed |
