  abstract	= {Preconditioned iterative solution methods are compared
		  with the direct Gaussian elimination method to solve dense
		  linear systems $A\mathbf{x} = \mathbf{b}$ which originate
		  from crack propagation problems, modeled and discretized by
		  boundary element (BEM) techniques.
		  
		  Numerical experiments are presented and compared with the
		  direct solution method available in a commercial BEM
		  package. The experiments show that the preconditioned
		  iterative schemes are competitive compared to the direct
		  solver with respect to both arithmetic operations required
		  and memory demands.}
