Ganymede’s grooved terrain likely formed during an epoch of global expansion, when unstable extension of the lithosphere resulted in the development of periodic necking instabilities. Linear, infinitesimal-strain models of extensional necking support this model of groove formation, finding that the fastest growing modes of an instability have wavelengths and growth rates consistent with Ganymed...

The focus of this study is on the characterization local plastic deformation and failure functionally graded 22MnB5 plates after hot stamping using an in situ approach. Various forming strategies at elevated temperatures are performed differentially tempered tools to locally tailor microstructure. By controlling cooling rate, as well martensitic ferritic–pearlitic microstructures obtained. Expe...

Retardation of necking under biaxial stretching of bilayer plates comprised of an elastomer layer bonded to a metal layer is studied. Substantial increases in necking limits and consequent energy absorption can be achieved in metal–elastomer bilayers for both quasi-static and dynamic stretching. The phenomena is tied to the fact that under stretching the incremental modulus of the elastomer rem...

Localized pattern formations and "two-phase" deformations are studied theoretically in soft compressible cylinders subject to surface tension axial loading through several force-controlled scenarios. By drawing upon known results for separate yet mathematically similar elastic localization problems, a concise family of analytical bifurcation conditions localized bulging or necking derived terms...

Previous linear bifurcation analyses have evidenced that an axially stretched soft cylindrical tube may develop infinite-wavelength (localized) instability when one or both of its lateral surfaces are under sufficient surface tension. Phase transition interpretations also highlighted the admits a final evolved ‘two-phase’ state. How localized initiates and evolves into state is still matter con...
