DOI: 10.1016/j.jmps.2020.103959
Abstract: Abstract Elastic thin shells are well-known for their highly unstable post-buckling, a response that exhausts their pressure bearing capacity and leads to catastrophic collapse. This paper examines elastic thin shells with a large axisymmetric imperfection… read more here.

DOI: 10.1142/s0219887819501482
Abstract: By employing exact Einstein–Yang–Mills (EYM) solution in [Formula: see text] dimensions we establish spherical thin-shells with mass and Yang–Mills charge. Remarkably these shells are stable against linear, radial perturbations with a barotropic fluid presented on… read more here.
