A method for LEFM analysis of RPV during SBLOCA [PDF]
International Journal of Pressure Vessels and Piping, 1986 Abstract A somewhat simplified two-dimensional linear elastic fracture mechanics (LEFM) model of the beltline of a reactor pressure vessel is presented. The fracture mechanics model used tends to be conservative in the sense that it ignores possible beneficial effects of warm prestressing and cladding. For LEFM studies that require a large number of

Fatigue Lifetime Assessment of HFMI‐Treated Welded Joints According to the Peak Stress Method
Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 3, Page 790-819, March 2026.ABSTRACT High‐frequency mechanical impact (HFMI) is an effective post‐weld treatment that enhances fatigue strength by inducing compressive residual stresses, localized strain hardening, and increasing weld toe radii. The peak stress method (PSM) was recently extended to evaluate the fatigue strength of HFMI‐treated steel joints under uniaxial loading ...

Manufacturing of PP‐Based Composite Sandwich Panels via Simultaneous Foaming and Skin‐Core Bonding
Polymer Composites, Volume 47, Issue 3, Page 2349-2362, 10 February 2026.One‐step CO2 physical foaming process for manufacturing thermoplastic sandwich panels: in‐situ expansion of a foaming‐grade PP core and fusion bonding with PP/glass fiber composite skins. ABSTRACT Sandwich panels are skin‐core‐skin structures commonly used in aerospace applications due to their high strength‐to‐weight ratio and flexural stiffness.

Engineering Reports, Volume 8, Issue 2, February 2026.A low‐cost clip gauge extensometer for crack mouth opening displacement was developed from accessible procedures and materials. Accuracy and repeatability comparable to commercial devices were demonstrated in calibration and fracture tests, enabling reliable measurement in CT specimens for resource‐constrained laboratories.

Stress Barriers and Their Impact on Rupture Propagation
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.Abstract Earthquake ruptures often exhibit complex behaviors, including abrupt arrest followed by delayed re‐nucleation. While on‐fault stress heterogeneity is a recognized contributing factor, as it can arrest or slow down rupture propagation, its interaction with propagating ruptures remains complex and not fully understood. Here, we study frictional

A Novel Approach for ∆K Estimation in the Fatigue Threshold Region Based on ΔKth and Kmax,th
Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 2, Page 653-662, February 2026.ABSTRACT A novel procedure, proposed by Kujawski and Vasudevan 1, has been evaluated as an alternative to the ASTM E647 standard for determining the ∆Kth and Kmax,th thresholds. This method relies solely on the actual propagation of cracks, which occurs only when both thresholds are satisfied simultaneously. For long cracks, a more efficient estimation
