Two-bay longitudinal crack arrest feature is the main aspect of design for damage tolerance of the pressurized fuselage cabin. Under fuselage pressurization load cycles, fatigue cracks develop at location of maximum tensile stress. There are locations on the airframe which are favorable for the initiation of longitudinal cracks.

Longitudinal Crack. There is a longitudinal crack between them, at the bottom of which some laterigrade fibers (called the corpus callosum) connect with the two hemispheres. …

In terms of crack morphology, the longitudinal crack presents four types: linear, offset, bifurcated and truncated. (2) Lengths of longitudinal cracks in most monitored sections exceed 100 m, and the most serious section is the DH high-speed K 88 (excavation section). Length of the longitudinal crack is 235 m within the monitoring …

The working principle of tertiary crushers varies depending on the type of crusher, but generally, they work by applying pressure to the material through compression or impact. VSI crushers work by throwing the material against a hard surface to produce a cubical-shaped product. Cone crushers and roll crushers work by compressing the …

The longitudinal crack sensitivity index is highest at 60–100 mm below the meniscus, and the position of an actual longitudinal crack agrees well with the calculated result. This illustrates the validity of the proposed method for predicting longitudinal cracks, and hence demonstrates the necessity of building the full-scale model integrated ...

Longitudinal cracking runs parallel to the pavement centerline (or laydown direction) and can be associated with reflective cracking from an underlying layer, poor joint construction or location (joints located in the wheel …

The results showed that the maximum improvement of cutting force, surface roughness and subsurface crack fracture depth by longitudinal torsional ultrasonic vibrations were 82.59%, 22.78% and 30.75%, respectively. A longitudinal torsional ultrasonic vibrations cutting force prediction model containing the parameters of tool, …

31 Introduction This chapter focuses on wheel-path longitudinal cracking that is fatigue-related. Figures 4.1 (a) and (b) show typical longitudinal cracks in the wheel-path. …

Cracks parallel to the pavement's centerline or laydown direction. Usually a type of fatigue cracking.

The correlation between the longitudinal crack occurrence and integrated heat transfer of the mold with data mining methods was investigated. Firstly, three kinds of support vector machine models based on principal component analysis with different input features were established to explore the effect of integrated heat transfer on the …

ever, the incidence of longitudinal corner crack was very high. Among 42 chamfered slabs sampled, 12 of them had longitudinal corner cracks between 0.3 and 1.3 m in length, while there was no longitudinal crack for the conventional slab. Typical morphology of longitudinal corner crack of the chamfered slab is shown in Fig. 5. The chamfered surface

The dynamics of a uniform wooden beam with a longitudinal crack is studied. The study aims at determining the variation of the MOE value as a function of the crack length. The MOE is determined from the bending vibrations at the lowest resonance frequencies, and the crack is taken as a cut along the axis of the beam with an increasing length. The …

WHEEL PATH LONGITUDINAL CRACKING. Record the length in meters of longitudinal cracking within the defined wheel paths at each severity level. Record the length in …

Monitoring longitudinal crack defects is of great significance in stabilizing and improving the slab quality. Herein, a monitoring model is developed to recognize the longitudinal crack defect of continuous casting slabs using principal component analysis (PCA) and support vector machine (SVM). First, the typical characteristics of the ...

Transverse corner crack was one of the difficult problems in the continuous casting production of microalloyed steel [1,2,3,4], peritectic steel [], and hypoperitectic steel [].Influence of composition on the hot ductility of steels and transverse corner crack was studied by Mintz [7, 8].Cause and solution for transverse corner crack were discussed …

crack strike, there are 912 longitudinal cracks, 349 inclined cracks and 1422 circumferential cracks. The ratio of each type of cracks is shown in Figure 2 and Figure 3.

Longitudinal Crack Weld Defect: During the welding of pipeline joints, longitudinal cracks can occur if proper welding procedures are not followed or if there are issues with material quality or joint preparation. These cracks manifest as fractures running parallel to the direction of the weld axis, typically in the heat-affected zone or fusion ...

After homogenized micro-crack crushing, a uniform distribution of cracks appeared on the concrete pavement, and the surface crushed zone could be observed, as shown in Fig. 18. The main crack developed along the longitudinal direction of the impact head and the branch cracks developed along the transverse direction.

Longitudinal cracking is a type of asphalt distress in which long, parallel cracks appear on the pavement's surface. These cracks usually run parallel to the centerline of the road or parking lot and are typically more than 1 foot in length. They can vary in width and depth, but they are generally narrow and deep compared to other …

The surface longitudinal cracks have been one of the most serious defects in the cast products. In this study, the surface longitudinal cracks are mainly attributed to poor lubrication for mold flux by crack, heat transfer of mold, and properties of mold flux analysis. Comparing with the primary mold flux (PMF), the properties of optimized mold ...
