In this section, we provide four case studies to show the result KDML can bring in PHM, including inductive experience, physical model, and signal processing. In each case study, we describe its knowledge source and representation, knowledge embedding approach, and experimental result. In this subsection, an empirical model informed learning method constructed by Li et al. [34] is described in detail, whose name is Coupling Competition Degradation based Deep Markov Model (C2D2M2).

Summary The very high cycle fatigue behavior of as-welded structural steel was investigated. Specimens failed from cracks initiating at the weld toe. A significant frequency effect was found using conventional fatigue testing. 1 Introduction The fatigue behavior of welded joints is a critical concern in structural integrity assessments of cyclically loaded structures as they are often the site of initiation and propagation of fatigue cracks [1].

1 INTRODUCTION Electron backscatter diffraction (EBSD) is a scanning electron microscopy (SEM) technique, providing important crystallographic information about the sample such as crystal orientation and grain size.1 Figure 1 shows the typical instrument geometry, where an EBSD pattern (EBSP) is formed from an electron beam incident on a crystal plane of a highly tilted sample.1 Conventionally, an EBSD data set is acquired by scanning an electron beam across the surface of a sample in a...
