Theoretical and Practical Implications Derived From the Formulation of the Theory of Critical Distances

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT The Theory of Critical Distances comprises several methodologies that allow fracture, fatigue, and stress corrosion cracking phenomena to be analyzed. Such methodologies are usually referred to as the Point Method (PM), the Line Method (LM), the Area Method (AM), and the Volume Method (VM).

Constitutive Models Based on Compressible Plastic Flows [PDF]

, 1983
The need for describing materials under time or cycle dependent loading conditions has been emphasized in recent years by several investigators. In response to the need, various constitutive models describing the nonlinear behavior of materials under ...

Precise Vibration Decoupling and Matrix Rigidification: A Dual Locking Strategy for Highly Efficient Photoluminescence

Aggregate, Volume 7, Issue 5, May 2026.
This work presents a dual strategy for constructing high‐efficiency photoluminescent materials. At the molecular level, vibration decoupling is suppressed through space charge transfer chromophores, boosting fluorescence. At the aggregate level, rigid polymer matrices protect and stabilize triplet excitons, enabling efficient and colorful room ...

Network Games With Triadic Interactions

International Economic Review, Volume 67, Issue 2, Page 605-632, May 2026.
ABSTRACT We propose a model for network‐mediated interactions incorporating higher‐order relationships such as triadic interactions. The marginal utility of an individual's action depends explicitly on endogenous actions of multiple units. Conditions ensuring a unique Nash equilibrium are derived using a variational inequality approach. We estimate the

Experimental Investigation on the Effect of Rubber Powder on Mechanical Properties of PVA Fiber Concrete

Advances in Civil Engineering, 2021
To verify the damping improvement by replacing partial sand with rubber powder in the concrete process, this study investigated the effects of the rubber powder (5%, 10%, 15%, and 20%) on the mechanical properties and micromechanism of polyvinyl alcohol (

Constitutive model for plasticity in an amorphous polycarbonate [PDF]

, 2007
A constitutive model for describing the mechanical response of an amorphous glassy polycarbonate is proposed. The model is based on an isotropic elastic phase surrounded by an SO(3) continuum of plastic phases onto which the elastic phase can collapse ...

The Dynamic Energy Band Model of Contact‐Separation and Sliding Mode Triboelectric Charging of Polymers at the Metal‐Polymer Interface

Advanced Science, Volume 13, Issue 21, 13 April 2026.
Triboelectric charge generation at polymer‐metal interfaces arises from the interplay of polymer mechanochemistry, polymer physical properties, and material transfer, where ion‐derived dipoles modulate the interfacial potential and mechanochemically generated electronic states and work function differences drive electron transfer, providing a unified ...

Triaxial Mechanical Properties and Micromechanism of Calcareous Sand Modified by Nanoclay and Cement

Geofluids, 2021
Calcareous sand is developed by the fracture of marine biological skeleton under the impact of seawater. Calcareous sand is not transported in the process of deposition. Therefore, calcareous sand retains the characteristics of marine biological skeleton,
