Abstract: A general method is presented for generating controlled rectilinear motion to any desired accuracy. The required motion is expressed in terms of a Fourier series whose coefficients are shown ...

Abstract: Expressions are derived for the bond stresses induced by a radially symmetric temperature distribution in spherical propellant grains bonded to spherical casings. Equations for the evaluation of ...

Abstract: First and second finite-difference expressions are derived for the first three derivatives of displacement with respect to time. The numerical results obtained by applying these difference expressions ...
