We investigate the buckling and post-buckling properties of a hyperelastic half-space coated by two layers when composite structure is subjected to uniaxial compression. In case with single layer, it known that shear modulus [Formula: see text] layer larger than half-space, linear analysis predicts existence critical stretch wave number, whereas weakly nonlinear threshold value ratio below whic...

Since 2014 Russian aggression Ukraine’s sovereignty and territorial integrity is considered as an act obvious violation international law well attempt to change current world order established after Soviet Union collapse when former republics gained full independence.
