Abstract: Post-buckling behavior of inelastic columns is analyzed by taking account of the reversed plasticity which follows elastic unloading in the convex side of the column with an increase of the lateral deflection. The effect ...

Abstract: Guided waves can be used in pipe inspection over long distances. Presented in this paper is a beam focusing technique to improve the S∕N ratio of the reflection from a tiny defect. Focusing ...

Abstract: Wave propagation across a pipe elbow region is complex. Subsequent reflected and transmitted waves are largely deformed due to mode conversions at the elbow. This prevents us to date from ...
