Crack Propagation on the Surface of the Bottleneck of a Pressure Vessel Considering the Initial Crack Angle

open access: yesApplied Sciences, 2022
In order to solve the impact on the accuracy of a life prediction model when the initial crack angle of the curved surface is not 0°, the traditional stress intensity factor model is revised by the non-linear regression analysis method, and an optimized ...

ANALYSIS OF APPROXIMATED CURVED CRACKS IN HOMOGENEOUS AND GRADED MATERIALS

open access: yesJournal of Engineering, 2009
In this paper two stages of analysis are studied. In stage I, the influence of crack shape on the crack-tip stresses, critical loads and subsequent propagation direction is investigated via a simple analytical model for cracks in homogeneous materials ...

Curved Fatigue Cracks Under Complex Loading [PDF]

open access: yesSAE Technical Paper Series, 2001
<div class="htmlview paragraph">A reliable and cost effective two-phase methodology is proposed to predict crack propagation life in generic two-dimensional structural components under complex fatigue loading. First, the usually curved fatigue crack path and its stress intensity factors are calculated at small crack increments in a specialized ...

Proposal of the rail profile selection method to reduce gauge corner cracking initiation by mitigating contact conditions of wheel and rail

open access: yesNihon Kikai Gakkai ronbunshu, 2022
The gauge corner cracking (GCC) occurs on heat treated rails of the high rail in curved sections with a radius of 600 to 800m. In case of GCC propagates deeply, it may cause rail breakage.

The Effect of the Free Surface on the Singular Stress Field at the Fatigue Crack Front

open access: yesJournal of Mechanical Engineering, 2017
Description of stress singularity in the vicinity of a free surface is presented. Its presence causes the retardation of the fatigue crack growth in that region and fatigue crack is being curved.

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...
