The Scaled Boundary Finite Element Method by John P. Wolf PDF

A unique computational method referred to as the scaled boundary finite-element procedure is defined which mixes the benefits of the finite-element and boundary-element tools : Of the finite-element strategy that no primary answer is needed and hence increasing the scope of program, for example to anisotropic fabric with no a rise in complexity and that singular integrals are kept away from and that symmetry of the consequences is instantly chuffed.

Example text

The formulae at 'the end of the two preceding sections can also be written as follows: 36 Df • f«D(logabs f) and Df • rec exp f*D(exp f). Replacing f In the former formula by a particular function f la called logarithmic derivation (or differentiation) of f. Similarly, replacing f In the latter formula by a particular function f might be called exponential derivation of f • We -apply the former. method with benefit whenever logabs f IB simpler than f. As an example of logarithmic derivation, we treat the power functions* From c - po m exp(c-log) it follows that log c-po « c*log which is Indeed simpler than c-po.

We apply the formula exp(f +g) « exp f*exp g to f * J and g • c. We obtain D[exp(J -t-c)] =D exp(J -»-,c)»D(J *c)»D exp(] +c)-l=D exp (J +e). On the other hand D[exp(J -»-c)] »D(exp J«exp c) «D(exp*exp c) *exp c*D exp. Thus, D exp(J -f c)sexp c*exp. Substituting 0 in this equality we obtain on the left side: D exp(J+c)0*D exp(0 + o)*D exp c on the right side: exp cO*D exp 0»exp c«D exp 0« Thus D exp c « exp c»D exp 0 fbr each constant o. If we have 54 a base of constant a It follows that D exp * exp*D exp 0* We see that the derivative of an exponential function Is a constant Multiple of the function* We shall postulate the existence of an exponential function for which D exp 0*1.

We shall read the symbol Sf *an ant 1 derivative of f* or 'an integral of f* Indicating by this expression the multi-valuedness of the operator S In contrast to the uni-valuedness of D. The latter Is expressed in the Implication If f - g, then Df » Dg which will be of basic Importance for the Algebra of Antiderivatives. Sf is what in the classical analysis is denoted by /f (x)dx while f ~g expresses the relation ff(x) = gf(x) for which the classical theory does not Introduce a special symbol. Only to some extent f -»g corresponds to what in classical integral calculus is denoted by f(x) a g(x) + const.
