These numerical solutions have been solved by modal superposition and by direct integration applying through a particularly built method together with the Newmark method. Finally, an experimental procedure for studying the influence that geometrical properties of viscoelastic joints have on the ...
Section 3.0, Transient Capability Verification, presents a set of comparisons between code calculations and analytical solutions for selected heat transfer and fluid flow problems. Section 4.0, Transient Capability Validation, presents comparisons between code calculations and experimental data obtained in ...
The computational procedures for parabolic and hyperbolic problems are discussed. The interpolation procedure for the solutions within a time step is given. Numerical examples are used to illustrate the validity of the present complex-time-step algorithms. Copyright 1999 John Wiley & Sons, Ltd. 展开...
Deng and King 2018). This solution, like the solution of other nonlinear diffusion-type equations, is called the self-similar solution of the first kind, in which the similarity variable is determined by dimensional analysis (Diez et al., 1992). For the self-similar solutions of the second ...
Multisim features a comprehensive suite of SPICE analyses for examining circuit behavior. These analyses range from the basic to sophisticated. Each analysis helps you to obtain valuable information such as the effects of component tolerances and sensiti
The numerical solutions are more time-consuming and usually face convergence and stability problems. These solutions are not convenient for practical well test analysis in Oilfield. Our motivation for this paper is to develop simply, quickly and stably analytical PTA solutions for finite-conductivity ...
A general and powerful method of finding numerical solutions of dynamic time-dependent problems in mechanics is based on the reduction to ordinary differential equations of the partial differential equations describing the problem. This reduction can be effected by means of finite-element or finite-diff...
