This book presents an overview of recent and emerging additive manufacturing (AM)
techniques and their applications. It explains several of the processes developed using …

In the past decades, Lamb waves (LW) have seen encouraging results when applied to non
destructive testing (NDT) and structural health monitoring (SHM), with important research …

基于动力特性的结构损伤检测方法在过去几十年中得到了迅猛发展. 该技术的核心思想在于结构
的振动特性(比如频率, 振型, 模态阻尼等) 是结构物理参数(如质量, 阻尼和刚度) 的函数 …

A fault diagnosis method based on genetic algorithms (GAs) and a model of damaged
(cracked) structure is proposed. For modeling the cracked-beam structure an analytical …

The aim of this paper is to introduce a new finite spectral element of a cracked Timoshenko
beam for modal and elastic wave propagation analysis. The proposed approach deals with …

In this paper, the effect of material-temperature dependent on the wave propagation of a
cantilever beam composed of functionally graded material (FGM) under the effect of an …

This paper develops and presents a technique on the identification of the damage location
and depth in a beam using a frequency contour method. Unlike the frequency contour …

A guided wave damage identification method using a model-based approach is proposed to
identify multiple cracks in beam-like structures. The guided wave propagation is simulated …

Nonlinear Output Frequency Response Functions (NOFRFs) are a series of one-
dimensional functions of frequency recently proposed by the authors to facilitate the analysis …

This paper brings together the principles, equations, and applications of damage modelling
and elastic waves propagation, both traditional and state-of-the-art in a review form. It begins …
