The evolution of supernova remnants (SNRs) is studied, with particular attention to the effect of magnetic fields with axisymmetric two-dimensional magnetohydrodynamical simulations. The evolution of magnetic SNRs is the same as non-magnetic ones in the adiabatic Sedov stage. After a thin shell is formed, the shell is driven by the pressure of the hot interior gas (bubble). Evolution in the pre...

A refined dynamic finite-strain shell theory for incompressible hyperelastic materials was developed by the authors recently. In this paper, we first derive associated linearized incremental theory, and then use it to investigate wave propagation in a fiber-reinforced tube that is subjected an axial pre-stretch internal pressure. We obtain dispersion relations both axisymmetric non-axisymmetric...

A summary is first presented of the conceptual difficulties and paradoxes surrounding plastic bifurcation buckling analysis. Briefly discussed are nonconservativeness, loading rate during buckling, and the discrepancy of buckling predictions with use of .I2 flow theory vs JZ deformation theory. The axisymmetric prebuckling analysis, including large deflections, elastic-plastic material behavior...

A dynamic statement and a method for numerically solving the buckling problems of elastoplastic shells revolution with filler in axisymmetric non-axisymmetric shapes under quasi-static loading are presented within framework two approaches. In first approach, problem elastic-plastic deformation an elastic combined torsion is formulated two-dimensional (generalized axisymmetric) formulation based...
