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.

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

Field Observations of Decreasing Rock Fracturing Rates Over Geologic Time
Journal of Geophysical Research: Earth Surface, Volume 131, Issue 1, January 2026.Abstract Rock fracturing regulates the topography, carbon cycle, geologic hazards, and infrastructure degradation of the Earth. Yet, there remains a paucity of constraints on long‐term fracturing behavior. Here we use field measurements of 2221 clasts across a range of environments and rock types to show that the number and total length of fractures in

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.Traditional fracture criteria only consider the singular terms in the Williams expansion and neglect higher‐order term coefficients, resulting in significant discrepancies between predicted and measured values. To advance the understanding of rock fracture mechanisms, this study introduces a generalized maximum tangential stress (GMTS) criterion by ...

A Review on the Fracture Toughness and Long‐Term Durability of Fly Ash–Based Cementitious Composites
Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.Fly ash is widely used as a supplementary cementitious material to reduce Portland cement consumption and enhance the long‐term performance of cementitious composites. However, meaningful comparison of fracture toughness and durability reported across published studies remains challenging because of differences in specimen geometry, testing methods ...
