MODELING OF FATIGUE CRACK PROPAGATION IN TITANIUM ALLOY TC4 MATERIAL BASED ON THE PERIDYNAMIC THEORY

open access: yesJixie qiangdu
In order to more accurately predict the fatigue crack propagation behavior of titanium alloy TC4 under cyclic load,a new prediction model based on peridynamics theory was proposed.Within a finite near-field radius,a material point damage model was ...

Soft and Adhesive Cardiac Patch for Electrophysiological and Contraction Measurement

open access: yesAdvanced Science, EarlyView.
This study developed an epicardial electronic patch with a modulus similar to that of the heart (approximately 65kPa), which can collect stable electrocardiogram signals and myocardial contractility on the surface of a dynamically beating heart. This is attributed to the hydrogen bond interaction formed between the amino and catechol groups in the ...

Toward Flexible Printed Electronics: A Spider‐Silk‐Inspired, Strong and Tough Thermoplastic Polyamide Elastomer

open access: yesAdvanced Science, EarlyView.
Inspired by spider silk, a bio‐inspired polyamide elastomer with a dynamic physical cross‐linking network is developed. Mimicking the rigid β‐sheet crystals and sacrificial hydrogen bonds of silk, the material achieves an exceptional balance of strength and toughness.

Covalent Bonds Reinforced Strength and Modulus of Heterocyclic Aramid Fiber by Interfacial Aminated‐MXene Nanosheets

open access: yesAdvanced Science, EarlyView.
We demonstrate the covalent bonds strategy to enhance the mechanical property of PBIA fiber by using interfacial MXene‐NH2 nanosheets. The MXene‐NH2 nanosheets with reactive amino sites that can serve as nucleating agents and chain anchors to enhance orientation, crystallinity and interchain interaction of PBIA fiber via strong interfacial amido ...
