Catheter Dwell Time and Its Risk of Failure for Adult Patients with Peripheral Venous Catheters [PDF]
Port Said Scientific Journal of Nursing, 2023 Background: Peripheral venous catheters, which are often used in adult patients, may have a critical threshold dwell length associated with a higher risk of catheter failure. Aim: This study aimed to assess catheter dwell time and its risk of failure for

The fracture behavior transitions in cold dwell fatigue of Ti-6Al-4V [PDF]
MATEC Web of Conferences, 2020 Ti-6Al-4V forged materials which had fine grain size and commercial billet which had moderate grain size and micro texture were prepared. Cold dwell fatigue tests were conducted using both materials, and dwell time condition was up to 1800s.

The rupture life prediction in cold dwell fatigue of Ti-6Al-4V based on the creep deformation [PDF]
MATEC Web of Conferences, 2020 Titanium a lloys have been found that the fatigue strength of Ti alloys decreases due to cold dwell fatigue (CDF) at room temperature. Ti and Ti alloys generate creep deformation at room temperature (T/Tm = 0.15).
