These alternate forms are easily found using Laplace notation; for example, if velocity, z˙, rather than displacement, z, was required as the response, then, since differentiation corresponds to multiplication by s, (3.5)(z˙F_)=sm⋅1(s2+2γωns+ωn2) If the acceleration, , was ...

A Laplace transform which is a constant multiplied by a function has an inverse of the constant multiplied by the inverse of the function. First shift theorem:
Equation 7.5 shows that in the Laplace domain, differentiation becomes multiplication by the Laplace variable s with the additional subtraction of the value of the function at t = 0. The value of the function at t = 0 is known as the “initial condition.” This value can be used, in eff...

∗b denotes element-by-element multiplication of the vectors a and b. For more techniques to deal with the singular integral operators we refer to [24, 25]. In general, it is necessary to choose specific quadrature rules for the Nyström method to be able to discretize the BIEs. ...
