The suitability of the calculus of finite differences applied to fourth order differential equations describing shell displacement behavior due to axisymmetric loading is determined. The difference formulation, using central difference methods and "fictitious" points associated with the end point, is shown ...
I am impressed with the quality of instruction and practice problems offered by Jenn. As a engineering student, I always utilize Calcworkshop as a the "first stop" to really understand and gain confidence in the subject. I credit my success in Calculus to Jenn and CalcWorkshop and making ...

For a more complete text about differential geometry of surfaces and tensor calculus, we refer the reader to Grinfeld (2013); and to Simmonds (2012) for a concise introduction to tensor analysis. 2.1. Differential geometry of surfaces Let S be a surface embedded in R3 (e.g. the middle ...
(48) and use of standard arguments of varia- tional calculus one obtains as Euler–Lagrange equations the equilibrium of stress resultants and couple resultants, the geo- metric field equation εg − ε = 0 and ψ = 0 in along with the static boundary conditions t = t¯ on σ . ...

which is one of SciPy’s integrate functions. I’m not quite sure of the specifics of how this works because I haven’t taken calculus, but essentially it solves our equations for what we need. First we initialize ret as an object of Odeint, then we run method T on it which solves ...
The resulting open spaces collect food, dental plaque and calculus and put the patient at greater risk to losing additional teeth in the future. 6. An inability to maintain and record the position of the pre-treatment soft tissue gingival anatomy found prior to tooth removal to the underlying ...
arc-length methodIn this work, a unified formulation of full geometrically nonlinear refined shell theory is developed for the accurate analysis of highly flexible shell structures. The tensor calculus is utilized to explicitly derive the linear and nonlinear differential operator matrices of the ...
