Stress field and fatigue evaluation method of V-notch composites based on N-SIF method

Cailiao gongcheng
The stress field of V-notch composite plates is simplified by introducing the equivalent strength factor as1. A semi-analytical formula for the stress field of single-edge V-notched composite plates is derived theoretically， and a simplified formula for ...

Advancing Human Skin Equivalents: The Crucial Role of Neurovascular Integration

Advanced Healthcare Materials, EarlyView.
This review discusses the importance of integrating vascular and peripheral nerve systems into human skin equivalents (HSEs) to better recapitulate native skin physiology. Recent advances in vascularized, innervated, and neurovascularized HSEs are highlighted, together with emerging bioengineering strategies, current challenges, and future ...

V-notch to Prevent Sliding of Crimpable Hook

Orthodontic Journal of Nepal, 2015
En-mass retraction of anterior teeth most commonly involves the use of crimpable hooks which often dislodge when retracting force is applied. A V-notch distal to the hook may prevent such sliding when sandblasting and dental adhesives are not ...

Delta-like 4 is indispensable in thymic environment specific for T cell development. [PDF]

, 2008
The thymic microenvironment is required for T cell development in vivo. However, in vitro studies have shown that when hematopoietic progenitors acquire Notch signaling via Delta-like (Dll)1 or Dll4, they differentiate into the T cell lineage in the ...

Self‐Healing Hydrogel‐Enabled Modular Assembly of Bilayered Skin Construct for Hair Follicle Regeneration

Advanced Healthcare Materials, EarlyView.
Self‐healing assembly of two cell‐laden hydrogel layers creates a biomimetic skin construct that restores both dermal and epidermal functions, resulting in accelerated wound healing and enhanced hair follicle regeneration in a full‐thickness skin wound model. ABSTRACT Alopecia remains a pervasive clinical challenge, largely owing to the limited ability

Singular behaviour near the tip of a sharp V-notch in a power law hardening material

, 1993
This paper presents an asymptotic analysis of the near-tip stress and strain fields of a sharp V-notch in a power law hardening material. First, the asymptotic solutions of the HRR type are obtained for the plane stress problem under symmetric loading ...

Damage Reduction of Explosively Driven Spallation by Machining V-Notch Rows on the Surfaces of 304 Stainless Steel Plates

Engineering Transactions, 2014
Plane detonation waves generated in the explosive PETN with use of wire-row explosion technique for initiation have been applied to study on spall behaviour for circular plates of 304 stainless steel, and the slanting surface effects on the damage ...

Can Elastomers Combine Stiffness, Toughness and Fatigue Resistance?

Advanced Materials, EarlyView.
This review studies how the molecular and macroscopic architecture of elastomers influence their mechanical properties including: stiffness, stretchability, toughness, fatigue resistance, and damping behavior. By linking the structure to performance, it proposes design principles for advanced elastomeric systems that combine mechanical properties ...

Study of V-notch fatigue strength based on affected depth approach

Comptes Rendus. Mécanique
In this work, the Affected Depth (AD) approach is employed to estimate the high cycle fatigue limit of AISI 416 steel weakened by notches. This approach is based on a critical depth parameter identified from the analysis of the stress distribution around

Soft Yet Tough Tanglemers Through Rapid Photopolymerization for DLP 3D Printing

Advanced Materials, EarlyView.
Soft yet tough tanglemers are produced through low‐initiator free radical photopolymerization and translated to DLP 3D printing. Systematic control over light intensity, initiator loading, and crosslink density reveals processing windows that balance printability, elasticity, toughness, and feature fidelity. ABSTRACT Additive manufacturing of compliant
