Physico‐Chemical Understanding of Plasticizers Interaction with P(VDF‐TrFE‐CFE) Electroactive Polymer

Macromolecular Materials and Engineering, EarlyView.
This study explores the effects of DNOP plasticizer on P(VDF‐TrFE‐CFE) terpolymers, revealing a strong synergy between chemical structure and physical properties. High TrFE bringing natural flexibility and CFE enhancing the plasticizer retention through theorized halogen bonds, ultra‐soft, crack‐free films of high permittivity and softness are ...

Is Weibull’s modulus really a material constant? Example case with interacting collinear cracks

International Journal of Solids and Structures, 2006
AbstractThe Weibull distribution is widely used to describe the scatter of the strength in brittle (but also quasi-brittle) materials, often assuming that the Weibull modulus is a “material constant”. One possible motivation of this perhaps comes from the classical Freudenthal’s interpretation of Weibull modulus depending on the crack size distribution,

A Peridynamic Framework for Modeling Progressive Failure in Porous Sandstone Indentation

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT A state‐based peridynamic model is proposed to simulate the failure mechanisms in porous rocks, using Bentheim sandstone as a specific example. Experimental observations reveal a transition from brittle to ductile failure under increasing triaxial compression. This behavior is attributed to pore compaction. The peridynamic model is enhanced to

From Microstructure to Macroscopic Performance: A Comprehensive Study on Low‐K Oxide‐Doped BNT–LST–NN Ceramics for Energy Storage

Rare Metals, EarlyView.
ABSTRACT Dielectric ceramics are popular for energy storage materials because of their rapid charge–discharge characteristics, whereas their low energy density and efficiency hinder their miniaturization and integration. In this work, the energy storage performance is significantly enhanced through introducing Al2O3 and TiO2 into the 0.425(Bi0.5Na0.5 ...

The Concept of Filament Strength and the Weibull Modulus

Journal of Testing and Evaluation, 1989
Abstract The strength of high-performance filaments is a complex parameter which can not be fully described with a single value. The Weibull model is used to describe the intrinsic statistical nature of the fracture strength. Possibilities and limitations of the Weibull model are illustrated.

Multifaceted Behavior and Functional Versatility of Ferritic Stainless Steels, Part I: Applications and Processing, a Review

steel research international, EarlyView.
This review investigates the processing‐microstructure‐property relationships in ferritic stainless steels (FSSs). It highlights advances in deformation behavior, heat treatments, surface modifications, and alloying effects. Theoretical models, including Johnson‐Mehl‐Avrami‐Kolmogorov, Arrhenius, nucleation theory, and diffusion theories, are discussed

Study on Electrical Properties of Silicone Rubber Insulation for Cable Accessories Under Mechanical Stretching

High Voltage, EarlyView.
ABSTRACT Silicone rubber (SR) is extensively used as insulation for cable accessories, directly affecting their design and operation. The distinctive feature of cable accessory insulation, operating under mechanical stretching, has not received sufficient attention in relevant standards and research.

Effect of Unit Cell Topology on Dielectric Properties of Periodic Lattice Materials Used for Functionally Graded Insulation

High Voltage, EarlyView.
ABSTRACT Periodic lattice material (PLM) is an innovative material system capable of rapidly and efficiently constructing functionally graded materials (FGMs). Among various PLM structures, triply periodic minimal surfaces (TPMS) exhibit numerous advantages, making TPMS‐based lattice materials a potential candidate to electrical FGMs.
