ANALYSIS OF APPROXIMATED CURVED CRACKS IN HOMOGENEOUS AND GRADED MATERIALS
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]
<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 ...

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