Ultrasonic Investigation of Tensile Fatigue Overloads in Fatigue Cracks

, 1989
The growth of a fatigue crack is generally modeled in terms of empirical rules such as the Paris law [1] which states that da/dN = A(ΔK)m where a is the crack length, N is the number of fatigue cycles at a particular stress intensity range ΔK and A and m are material constants. Recently, evidence has accumulated that establishes that the full excursion

Enhanced Infection Resistance and Regenerative Healing of Titanium Implants via Peptide‐Loaded Biodegradable Coatings

Advanced Materials Technologies, EarlyView.
This study presents a new biodegradable coating for titanium implants using a natural antimicrobial peptide, caerin 1.9. Applied via solvent casting, the coating offers sustained antibacterial protection and promotes healing. Tested on 3D‐printed porous titanium scaffolds, it effectively prevented infection—including against resistant bacteria—while ...

Extreme‐Temperature Resistant, Flexible, and Sensitive Strain Sensor for Aerospace Parachute Deployment

Advanced Materials Technologies, EarlyView.
In this study, we report a resistive‐type strain sensor fabricated using single‐walled CNTs, are used layer using the pray technique to deposit as conductive, and UV‐resin was spin‐coated as a protection layer. The sensor functioned in harsh temperature variation conditions from −50°C to 125°C without deterioration.
