The Laplace transform is performed on a number of functions, which are – impulse, unit impulse, step, unit step, shifted unit step, ramp, exponential decay, sine, cosine, hyperbolic sine, hyperbolic cosine, natural logarithm, Bessel function. But the greatest advantage of applying the Laplace ...
the method usingLaplace transformsis particulary useful in finding the solution”,又说道“Of course the problem can be solved by a number of other methods; but the Laplace-transform method appeals especially to the engineering scientist in that it reduces all problems...
Application of the Laplace transform on the finite element equations of motion for a discrete system, directly or in conjunction with modal analysis, reduces them to a system of algebraic equations which are solved numerically in the transform domain. The Laplace transformed equations of motion for ...
