Structural health monitoring is the technique which evaluate and analyze materials in the
production and service process. In this paper, the basic principles and characteristics of …

Wave reflection which is inevitable in the explosion plays a significant role in blast-induced
fracture. In this paper, transient effects of vertical (P 1 P) and horizontal (P 2 P) reflected blast …

In this paper, the multi-crack propagation within polymethyl methacrylate (PMMA) plates
under out-of-plane impact is experimentally investigated. First, the dynamic propagation …

Instability failure of rock masses containing joints has always been a hot topic in rock
mechanics. To study the mechanical failure mechanism of rock masses containing internal …

Both caustics and strain gage methods are shown to be effective in the determination of
mode I stress intensity factor (SIF) at the crack tip. However, there is a lack of investigation …

In the last few decades, there has been a significant increase in interest in develo**,
constructing, and using structural health monitoring (SHM) systems. The classic monitoring …

In this paper, a high-precision and flexible intrinsic and extrinsic parameters calibration
method for non-overlap** array cameras is proposed. In the camera array system, each …

High-resolution imaging devices are of interest in the development of accurate 3D vision
systems. However, it is challenging to achieve a balance between the image capturing …

The dynamic caustic method and numerical simulation method were used to study explosive
stress field of cylindrical blasting with bottom initiation. The explosive stress distribution of …

In the surface imaging of underwater structures, long working distance will reduce image
quality due to the turbidity of water. To acquire high definition and large field of view (FOV) …
