Experimental and numerical study on damage detection in an L-joint using guided wave propagation
TL;DR: In this paper, the authors considered longitudinal and flexural wave propagation in a steel L-joint and compared the usefulness of axial and flexurant wave propagation for non-destructive damage detection for this typical structural component.

Numerical Laplace Transformation and Inversion
TL;DR: In this article, an efficient basis for the numerical manipulation of the Laplace transform for the purpose of solving transient problems which are not amenable to conventional analytic manipulation is presented, although the underlying material is not new, the manner of presentation is such as to expose important matters of detail.
