Analysis of weak magnetic nondestructive testing for cracks in the top beam of hydraulic support
Gong-kuang zidonghua, 2022 In view of the complicated operation of the current crack detection method of hydraulic support, a weak magnetic nondestructive detection method for cracks in the top beam of hydraulic support based on geomagnetic field excitation is proposed.

An Adaptive Crack Width Prediction for Flexural Steel Reinforced UHPC Beams
International Journal of Concrete Structures and Materials, 2023 The crack pattern of steel reinforced ultrahigh performance concrete (UHPC) beam is usually characterized by many densely distributed fine cracks (i.e., multiple microcracks) along with localized macrocrack, and the crack width development rate along the

Crack widths close the reinforcement [PDF]
IABSE Reports, 2007 <p>Currently used design methods predict that the crack widths at the concrete surface increase significantly with concrete cover. Requirements concerning limitation of crack widths therefore makes it difficult to use large concrete covers, which otherwise is desirable to reduce the corrosion of reinforcement.

Buoyancy-driven crack propagation: the limit of large fracture toughness [PDF]
, 2007 We study steady vertical propagation of a crack filled with buoyant viscous fluid through an elastic solid with large effective fracture toughness. For a crack fed by a constant flux Q, a non-dimensional fracture toughness K=Kc/(3μQm3/2)1/4 describes the

Assessment of Cracking Widths in a Concrete Wall Based on TIR Radiances of Cracking [PDF]
Sensors, 2020 The techniques of concrete crack detection, as well as assessments based on thermography coupled with ultrasound, have been presented in many works; however, they have generally needed an additional source of thermal infrared (TIR) radiance and have only been applied in laboratories.
