TL;DR: In this paper, a single-director shell model is proposed for numerical simulation. But the model is not suitable for nonlinear shell-like structures and it does not handle the curvature of the mid-surface of the shell.
Abstract: This chapter introduces a single-director shell model as a specific approximation to the nonlinear mechanical behavior of thin, shell-like, structures. The primary goal of this chapter is to present that model in a way that is optimally suited for numerical implementation. As with the earlier discussion of linear shell theory, a set of dynamic shell balance equations determine the deformation of the shell in terms of surface quantities. Furthermore, the formulation avoids geometric complexities associated with the curvature of the mid-surface, such as the Riemannian connection of the mid-surface or Christoffel symbols (often present in nonlinear shell theories) through the choice of a specific parametrization of the balance equations. With this parametrization, numerical implementation by the finite element method followed naturally. The finite element implementation of nonlinear shell theory is illustrated with a four-node quadrilateral element.

TL;DR: In this article, a semi-infinite, elastic, circular cylindrical shell is subjected to two uniform, radial pressure pulses, one a step pulse and the other a short-duration, rectangular pulse, and the results for the stresses emanating from both a clamped support and a simple support are presented for a Timoshenko-type shell theory and a shell bending theory.
Abstract: A semi-infinite, elastic, circular cylindrical shell is subjected to two uniform, radial pressure pulses, one a step pulse and the other a short-duration, rectangular pulse Solutions for the stresses emanating from both a clamped support and a simple support are presented for a Timoshenko-type shell theory and a shell bending theory Results from the Timoshenko-type theory are obtained using the method of characteristics, and results from the shell bending theory are obtained using integral transform techniques Numerical results from both shell theories are presented for the bending stress and the shear stress resultant Results show that the effects of rotary inertia and shear deformation are important only in the vicinity of the wave fronts However, if the duration of the pressure pulse is short, maximum stresses can occur in the vicinity of the wave fronts where a Timoshenko-type shell theory is required for realistic response predictions

TL;DR: In this article, the effects of slip velocity and aligned Magneto hydro-dynamic on Jeffrey fluid which passing across a stretching sheet with Newtonian heating boundary condition are investigated, and the results from this project will enhance the knowledge in non-Newtonian fluid problem via mathematical approach.
Abstract: Objectives: Effects of slip velocity and aligned Magneto hydro-dynamic on Jeffrey fluid which passing across a stretching sheet with Newtonian heating boundary condition are investigated. Methods/Statistical Analysis: Governing partial differential equations are first transformed into ordinary differential equation by applying the similarity transformations before undergo computation process using y bvp4c in MATLAB. Findings: For validation purposes, the present results are comparing with the outcome from previous publications for the case Constant Wall Temperature (CWT) and it shows a very strong agreement on the values of −θ′(0) . From the study, the increasing on the values of magnetic parameter, M drop the fluid velocity for the range value of boundary layer thickness 0 3.5 , the value of fluid velocity is increasing on the larger magnetic parameter. However, the distribution on temperature of fluid shows an opposite trend as compare with fluid velocity. On the range of 0 2.5 it evidently reduce the velocity of fluid. The fluid temperature is high at smaller values of Deborah number. The distribution on velocity and temperature of fluid presented in this article are strictly asymptotically fulfilling the boundary conditions which then contribute to the adequate of the present results. Application/Improvements: The results from this project will enhance the knowledge in non-Newtonian fluid problem via mathematical approach.

TL;DR: In this paper, the authors used momentum balance models to predict hold up and pressure drop for both annular and stratified regimes, and found that the momentum balance calculation tended to under predict both the hold-up and pressure-drop.
