Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

Advanced Materials, EarlyView.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.

Localized Temperature Monitoring in Mouse Brain during Light Delivery via a Non‐Planar Tapered Fiber‐Integrated µRTD Sensor

Advanced Materials, EarlyView.
We report a multifunctional tapered optical fiber integrating a conformal micro‐resistance temperature detector (µRTD) for local, real‐time thermometry during optical stimulation. The platform combines light‐delivery and temperature sensing within a minimally invasive footprint, enabling detection of sub‐degree cortical heating under representative ...

Shear behavior of human skull bones

Journal of the Mechanical Behavior of Biomedical Materials, 2021
A shear-punch test (SPT) experimental method was developed to address the lack of shear deformation and failure response data for the human skull as a function of local bone microarchitecture. Improved understanding of skull deformation and fracture under varying stress-states helps implement mechanism-based, multi-axial material models for finite ...

The Behavior of Fabrics in Shear

Textile Research Journal, 1968
An analysis has been made of the geometrically similar tests of bias extension and sim ple shear for plain-woven fabrics. This analysis makes possible calculation of the values of the equivalent shear strain and equivalent shear stress, corresponding to measured values of tensile strain and tensile stress in bias extension.

Modeling Shear Behavior in the Annulus Fibrosus

ASME 2008 Summer Bioengineering Conference, Parts A and B, 2008
An accurate constitutive law for the annulus fibrosus (AF) is critical to modeling the complex loads and deformations of the intervertebral disc. In the healthy disc, the loads applied to the AF are primarily a combination of tension and torsion. Several researchers [1–5] have developed nonlinear strain energy functions to model the AF using the fiber ...

The Behavior of Fabrics in Shear

Textile Research Journal, 1967
The effect of heat-setting on the properties of a nylon monofil fabric in shear has been investigated, and considerable changes have been found to occur. These changes particularly depend on whether heat-setting is done with the specimen held at fixed dimensions or allowed free contraction.

Shear Behavior of Bovine Scleral Tissue

Journal of Biomechanical Engineering, 2014
Ocular tissue properties have been widely studied in tension and compression for humans and a variety of animals. However, direct shear testing of the tissues of the sclera appear to be absent from the literature even though modeling, analyses, and anatomical studies have indicated that shear may play a role in the etiology of primary open angle ...

Dynamic behavior of lung parenchyma in shear

Journal of Applied Physiology, 1996
Dynamic shear properties of excised rabbit lungs were studied by measuring creep deformation after application of a step indentation force to the pleural surfaces by a rigid cylindrical punch. The punch diameter was 9.5 mm, and punch forces were 2,4, and 6 g.

Bolted shear connectors in steel–concrete composite structures: Shear behavior

Structures, 2023
The use of bolted shear connectors is of great importance to the sustainable development of steel–concrete composite structures. In this paper, an experimental program consisting of four push-out specimens is performed to investigate the effects of bolt length and fabrication method of concrete slabs on the shear behavior of single-nut embedded bolted ...

Shear-resistant behavior of light composite shear wall

Journal of Central South University, 2015
Shear test results for a composite wall panel in a light composite structure system are compared with test results for shear walls in Japan. The analysis results show that this kind of composite wall panel works very well, and can be regarded as a solid panel.
