A discrete predator-prey system is presented. We study the existence and stability of the fixed point system. The conditions of existence of Flip and Neimark-sacker bifurcation is the system are derived. By using numerical continuation methods and MatContM toolbox. We compute bifurcation curves of fixed points and cycles with periods up to 32 under variation of one and to parameters, and comput...
2-d and axisymmetric navier-stokes equations are solved using reiman-roe solver with different limiters for second-order accurate schemes. the results were obtained for supersonic viscous flows over semi-infinite axisymmetric and 2-d bodies. the free stream mach numbers were 7.78 and 16.34. the stability of roe method with different limiters and entropy conditions were considered. the results s...
Abstract The prediction of the buckling resistance shells is subject to uncertainty since it depends significantly on initial geometric imperfections caused by fabrication process. However, load case vacuum or uniform external pressure has not yet been extensively studied. Stress design approaches implement a reduction factor alpha that accounts for effect imperfections. This assumed be general...
in this paper, a thermoelasticity solution for steady state response of thick cylinders which are subjected to pressure and external heat flux in inner surface is presented. displacement field obeys the kinematics of the first order shear deformation theory (fsdt). it is assumed that the temperature varies both along the length and the thickness. the variation of the temperature occurs linearly...
in reality, most structures involved in geotechnical engineering are three dimensional in nature, and although in many, plane strain or axisymmetric approximations are reasonable, there are some, for which 3-d treatment is required. the quantity of data, and the size of the various vectors and matrices involved in such analysis, increase dramatically. this has sever implications for computer r...

Abstract We provide an extension to previous analysis of the localised beading instability soft slender tubes under surface tension and axial stretching. The primary questions pondered here are as follows: what loading conditions, if any, can bifurcation into circumferential buckling modes occur, do such solutions dominate localisation periodic modes? Three distinct boundary conditions consider...
Abstract In this work, an elastic-damage evolution analysis is carried out for a cylinder under torsion made of material obeying gradient damage model with softening. Both semi-analytical and asymptotic approaches are developed to analyze the elastic, axisymmetric bifurcation stages. We show existence fundamental branch where field asymmetric localized within finite thickness from boundary. By ...
We study the linear stability of bubbles in a capillary tube under external flow. Yu et al. ( J. Fluid Mech. , vol. 911, 2021, pp. 1–19) showed that rich variety bubble dynamics occurs when downward flow is applied, opposing buoyancy-driven ascent bubble. They found experimentally and numerically existence two branches solutions overlap over finite range number cases where Reynolds small Bond l...
