Electrostatically Reinforced Double Network Granular Hydrogels
Advanced Science, Volume 12, Issue 20, May 29, 2025.Electrostatically reinforced double network granular hydrogels (DNGHs) with cartilage‐like fracture energy are introduced. An empirical model predicts the composition‐dependent fracture energy based on dissipation zone size, contact area, and inter‐particle adhesion energy. Thanks to their granular structure and the inter‐particle attraction, the DNGHs

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.Limestone or river aggregates have been traditionally used as aggregates in ready‐mixed concrete from the past to the present. The depletion of these natural aggregates used in ready‐mixed concrete has led the concrete industry to investigate aggregate resources and search for alternative aggregates.

Fracture Assessment of Weld Joints of High-Strength Steel in Pre-Strained Condition
Applied Sciences, 2019 Unstable fractures tend to occur after ductile crack initiation or propagation. In most collapsed steel structures, a maximum 15% pre-strain was recorded, at the steel structural connections, during the great earthquake of 1995, in Japan. Almost-unstable

A Numerical Study of the Effect of Isotropic Hardening Parameters on Mode I Fatigue Crack Growth
Metals, 2020 The consideration of plastic crack tip opening displacement (CTOD, δp), as a crack driving force has given us the opportunity to predict fatigue crack growth (FCG) rate numerically, and, therefore, to develop parametric studies focused on the effect

Advanced Engineering Materials, Volume 26, Issue 16, August 2024.We measured two values of fracture toughness for X65 steel in air (KQ of 369 and 487 MPa√m$\sqrt{} \text{m}$) and two essentially American Society for Testing of Materials–valid values of fracture toughness of KJ1C of 150 and 189 MPa√m$\sqrt{} \text{m}$ for X65 subjected to in situ hydrogen charging thought to be equivalent to a hydrogen gas pressure ...

A strain-based approach to study interaction between non-coplanar through-thickness edge notches
, 2018 Structural integrity assessment procedures to assess the effect of interaction between multiple adjacent flaws normally consist of two stages. First, alignment rules categorize non-coplanar flaws as aligned or non-aligned.

Engineering Reports, Volume 6, Issue 8, August 2024.In present research the fracture behavior of carbon fabric‐epoxy composites was evaluated with the addition of 0.1, 0.2, 0.5, and 0.75 weight percentages of carbon nano tubes at different temperatures. Abstract In present research the fracture behavior of carbon fabric‐epoxy composites (CE composites) was evaluated with the addition of 0.1, 0.2, 0.5 ...

Influence and evaluation of constraint on fracture toughness in pipeline research [PDF]
, 2012 Accessing nowadays fossil fuel reserves requires a strain-based design approach. Within such design, the ductile tearing resistance is a key parameter in assessing the defect tolerance. To determine this tearing resistance, full scale (pressurized) tests

Experimental and numerical analysis of deformation patterns in notched heterogeneous welds [PDF]
, 2017 Standardized weld flaw assessment techniques assume the weld region to be homogeneous which is a strong idealisation of reality. Characterising the effects of heterogeneous properties of welds through the analysis of deformation patterns and slip lines ...
